ELECTION OF DIRECTORS

Nominees for Election as Directors of Sonic

Sonic’s Board of Directors currently consists of ten directors and is divided into three classes. On February 9, 2006, the Board of Directors amended our bylaws (as amended, the “Bylaws”) to phase out the classified board. Consequently, beginning at the Annual Meeting, the director nominees chosen to succeed those directors whose terms expire at an annual meeting of stockholders will be elected by the stockholders for a one-year term expiring at the next annual meeting of stockholders. Any director appointed by the Board of Directors as a result of a newly created directorship or to fill a vacancy on the Board of Directors will hold office until the next annual meeting of stockholders.

Messrs. Bruton Smith, Rachor, Brooks and Capo belong to the class of directors whose term expires at the Annual Meeting. The directors whose terms will expire in 2007 include Messrs. B. Scott Smith, Benton and Belk and the directors elected at the Annual Meeting. Beginning with the 2008 annual stockholders meeting, all directors’ terms will expire and their successors will be elected at each annual stockholders meeting thereafter.

At the Annual Meeting, we intend to vote the proxies in the accompanying form for the election of O. Bruton Smith, Jeffrey C. Rachor and William R. Brooks to the Board of Directors. Messrs. Bruton Smith, Rachor and Brooks have consented to serve, if elected, for a one year term until the 2007 annual meeting of stockholders or until his successor is elected and qualified, except as otherwise provided in our Charter and Bylaws. All of the nominees are presently directors of Sonic. Mr. Capo is not standing for re-election as a director of Sonic. As a result, two seats on the Board of Directors will be vacant following the Annual Meeting. Because the Nominating Committee of our Board of Directors has not selected a qualified candidate or candidates, the Board of Directors has elected not to fill these vacancies at the Annual Meeting. If for any reason any nominee named above is not a candidate when the election occurs, we intend to vote proxies in the accompanying form for the election of the other nominees named above and may vote them for any substitute nominee or, in lieu thereof, our Board of Directors may reduce the number of directors in accordance with our Charter and Bylaws.

Mr. Rewey’s term as a director of Sonic will expire at the 2008 annual stockholders meeting.

Board and Committee Member Independence

Because Mr. Bruton Smith holds more than 50% of the voting power of Sonic’s Common Stock, Sonic qualifies as a “controlled company” for purposes of the NYSE’s listing standards and is, therefore, not required to comply with all of the requirements of those listing standards, including the requirement that a listed company have a majority of independent directors. Nevertheless, Sonic is committed to having its board membership in favor of independent directors as evidenced by Sonic’s Corporate Governance Guidelines.

Our Board of Directors has determined that currently a majority of Sonic’s directors, including Messrs. Belk, Benton, Capo, Doolan, Heller and Rewey, and all of the members of Sonic’s board committees, are “independent” within the meaning of the NYSE’s current listing standards. The Board’s determination was based on its assessment of each director’s relationship with Sonic and the materiality of that relationship in light of all relevant facts and circumstances, not only from the standpoint of the director in his or her individual capacity, but also from the standpoint of the persons to which the director is related and organizations with which the director is affiliated. The Board of Directors applied Categorical Standards for Determination of Director Independence, which the Board adopted to assist it in evaluating the independence of each of its directors. The Board of Directors determined that each of the independent directors met these Categorical Standards for Determination of Director Independence. A copy of Sonic’s Categorical Standards for Determination of Director Independence is included as Annex A to this proxy statement.

Board Meetings and Committees of the Board

Attendance at Board and Committee Meetings. Our Board of Directors held five meetings during 2005. Each of the directors attended 75% or more of the aggregate number of meetings of the Board and committees of the Board on which the director served.

Executive Sessions of the Board of Directors. The non-management directors meet in executive session without members of management present prior to or after each board meeting. Mr. Belk, as lead independent director, presides over these executive sessions of non-management directors.

Attendance at Annual Meetings of Stockholders. Pursuant to the Board of Directors’ policy, all directors are strongly encouraged to attend our annual stockholders meetings. All of our directors attended last year’s annual stockholders meeting, other than Mr. Doolan who was not a director at the time of last year’s annual stockholders meeting.

Committees of the Board of Directors and their Charters. The Board of Directors of Sonic has three standing committees: the Audit Committee, the Compensation Committee, and the Nominating and Corporate Governance Committee (the “NCG Committee”). Each of these committees acts pursuant to a written charter, which was adopted by the Board of Directors and most recently amended in February 2006.

The Audit Committee currently consists of Messrs. Capo (chairman), Belk, Doolan and Heller. The Compensation Committee currently consists of Messrs. Rewey (chairman), Belk, Benton and Heller. The NCG Committee currently consists of Messrs. Benton (chairman), Capo, Doolan and Rewey. Set forth below is a summary of the principal functions of each committee.

Audit Committee. The Audit Committee appoints Sonic’s independent accountants, reviews and approves the scope and results of audits performed by them and the Company’s internal auditors, and reviews and approves the independent accountant’s fees for audit and non-audit services. It also reviews certain corporate compliance matters and reviews the adequacy and effectiveness of the Company’s internal accounting and financial controls, its significant accounting policies, and its financial statements and related disclosures. A more detailed description of the Audit Committee’s duties and responsibilities can be found in its charter. A copy of the Audit Committee Charter, which was amended and restated by the Board of Directors in February 2006, is attached as Appendix B to this proxy statement. Our Board of Directors has determined that each of Messrs. Capo, Belk, Doolan and Heller qualifies as an “audit committee financial expert” as defined by the current rules of the SEC, is “financially literate” as that term is defined by the rules of the NYSE, has accounting or related financial management expertise and is “independent” as defined in SEC Rule 10A-3(b)(1) and Section 303A.02 of the NYSE Listed Company Manual. The Audit Committee met ten times during 2005.

Audit Committee Report

The Audit Committee is appointed by the Board of Directors to assist the board in fulfilling its oversight responsibilities relating to Sonic’s accounting policies, reporting policies, internal controls, compliance with legal and regulatory requirements, and the integrity of Sonic’s financial reports. The Audit Committee manages Sonic’s relationship with Sonic’s independent accountants, who are ultimately accountable to the Audit Committee. The Board of Directors has determined that each member of the Audit Committee is “financially literate” as such term is defined by the rules of the New York Stock Exchange (“NYSE”) and “independent” as such term is defined by the current rules of the NYSE and the Securities and Exchange Commission.

The Audit Committee reviewed and discussed the audited financial statements of Sonic as of and for the year ended December 31, 2005 with management and the independent accountants. Management has the responsibility for preparing the financial statements, certifying that Sonic’s financial statements are complete, accurate, and prepared in accordance with generally accepted accounting principles, and implementing and maintaining internal controls and attesting to internal control over financial reporting. The independent accountants have the responsibility for performing an independent audit of the financial statements in accordance with generally accepted auditing standards and expressing an opinion on the effectiveness of internal control over financial reporting and management’s assessment of the effectiveness of internal control over financial reporting. The Audit Committee also discussed and reviewed with the independent accountants all

communications required by generally accepted auditing standards, including those described in SAS No. 61, as amended by SAS No. 90, “Communication with Audit Committees” and those described in SAS No. 99 “Consideration of Fraud in a Financial Statement Audit.” With and without management present, the Audit Committee discussed and reviewed the results of the independent accountants’ audit of the financial statements.

During 2005, the Audit Committee met ten times, including meetings to discuss the interim financial information contained in each quarterly earnings announcement for the quarters ended December 31, 2004, March 31, 2005, June 30, 2005 and September 30, 2005 with the chief financial officer and the independent accountants prior to public release. In addition, the Audit Committee regularly monitored the progress of management and the independent accountants in assessing Sonic’s compliance with Section 404 of the Sarbanes-Oxley Act, including their findings, required resources and progress throughout the year.

In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from the independent accountants the written disclosures and the letter from the independent accountants required by Independence Standards Board Standard No. 1, “Independence Discussions with Audit Committees.” The Audit Committee discussed with the independent accountants the independent accountant’s independence and met separately with management, internal auditors and the independent accountants to discuss, among other things, the adequacy and effectiveness of Sonic’s internal accounting and financial controls, the internal audit function’s organization, responsibilities, budget and staffing and reviewed with both the independent accountants and the internal auditors their audit plans, audit scope, and identification of audit risks.

Based on these reviews and discussions with management and the independent accountants, the Audit Committee recommended to the Board and the Board approved that Sonic’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2005 for filing with the Securities and Exchange Commission. The Committee also recommended the reappointment of the independent accountants, Deloitte & Touche LLP, and the Board concurred in such recommendation.

Compensation Committee. The Compensation Committee administers certain compensation and employee benefit plans of Sonic, annually reviews and determines compensation, including annual salaries, bonus performance goals, bonus plan allocations, stock option grants and other benefits, direct and indirect, of all executive officers of Sonic. The Compensation Committee administers the Sonic Automotive, Inc. 1997 Stock Option Plan (the “Stock Option Plan”), the Sonic Automotive, Inc. Employee Stock Purchase Plan, the Sonic Automotive, Inc. Incentive Compensation Plan (the “Incentive Compensation Plan”), the Sonic Automotive, Inc. 2004 Stock Incentive Plan (the “Stock Incentive Plan”) and certain other employee stock plans, approves individual grants of equity-based compensation under the plans it administers and periodically reviews Sonic’s executive compensation programs and takes action to modify programs that yield payments or benefits not closely related to Sonic’s or its executives’ performance. The Board of Directors has determined that all committee members are “independent” as defined in the current listing standards of the NYSE. The Compensation Committee met four times during 2005.

Nominating and Corporate Governance Committee. The NCG Committee is responsible for identifying individuals who are qualified to serve as directors of Sonic and for recommending qualified nominees to the Board of Directors for election or re-election as directors of Sonic. The NCG Committee will consider director nominees submitted by stockholders in accordance with the provisions of Sonic’s Bylaws. The NCG Committee is also responsible for recommending committee members and chairpersons of committees of our Board of Directors and for establishing a system for, and monitoring the process of, performance reviews of the Board of Directors and its committees. Finally, the NCG Committee is responsible for developing and recommending to the Board of Directors a set of corporate governance principles applicable to Sonic and for monitoring compliance with Sonic’s Code of Business Conduct and Ethics. The Board of Directors has determined that all committee members are “independent” as defined in the current listing standards of the NYSE. The NCG Committee met three times during 2005.

How to communicate with the Board of Directors and Non-Management Directors. Stockholders wishing to communicate with our Board of Directors, or any of our individual directors, including the lead independent director presiding over non-management executive sessions, may do so by sending a written communication addressed to the respective director(s) in care of Sonic Automotive, Inc., 6415 Idlewild Road, Suite 109, Charlotte, North Carolina 28212. Stockholders wishing to communicate with our non-management directors as a group may do so by sending a written communication to William I. Belk, as lead independent director, at this address. Any communication addressed to any director that is received at Sonic’s principal office will be delivered or forwarded to the respective director(s) as soon as practicable. Any communication that does not contain delivery instructions from the stockholder will be forwarded to the Chairman of the Board of Directors.

Stockholder Nominations of Directors

Stockholders may recommend a director candidate for consideration by the NCG Committee by submitting the candidate’s name in accordance with provisions of our Bylaws that require advance notice to Sonic and certain other information. In general, under the Bylaws, the written notice must be received by Sonic’s Corporate Secretary not less than sixty (60) and not more than ninety (90) days prior to the annual meeting. The notice must contain, among other things, the nominee’s name, date of birth, business and residential address and the information that would be required to be disclosed about the nominee pursuant to the SEC’s rules in a proxy statement and, with respect to the stockholder submitting the nomination and anyone acting in concert with that stockholder, the name and business address of the stockholder and the person acting in concert with the stockholder, a representation that the stockholder is a record holder of Voting Stock, a description of all arrangements, understandings or relationships between or among the stockholder, any person acting in concert with the stockholder and the nominee and the class and number of shares of Voting Stock beneficially owned by the stockholder and any person acting in concert with that stockholder. A stockholder who is interested in recommending a director candidate should request a copy of Sonic’s Bylaw provisions by writing to Stephen K. Coss, Senior Vice President, General Counsel and Secretary, at Sonic’s principal executive offices.

The NCG Committee has a process of identifying and evaluating potential nominees for election as members of the Board, which includes considering recommendations by directors and management and may include engaging third party search firms to assist the NCG Committee in identifying and evaluating potential nominees. The NCG Committee has adopted a policy that stockholder nominees for director will be treated the same as nominees submitted by other directors or management.

As set forth in Sonic’s Bylaws, Sonic’s Corporate Governance Guidelines and the Charter of Sonic’s Nominating and Corporate Governance Committee, the NCG Committee considers potential nominees for directors from all sources, develops information from many sources concerning the potential nominee, and makes a decision whether to recommend any potential nominee for consideration for election as a member of the Board. Sonic’s qualification standards for directors are set forth in its Corporate Governance Guidelines. These standards include the director’s or nominee’s:

SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected the firm of Deloitte & Touche LLP to serve as the principal independent registered public accounting firm of Sonic for the fiscal year ending December 31, 2006. Deloitte & Touche LLP has acted in such capacity for Sonic since its organization in 1997.

Representatives of Deloitte & Touche LLP will attend the Annual Meeting. They will have an opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

8

Stockholder ratification of the Audit Committee’s selection of Deloitte & Touche LLP as our independent registered public accounting firm is not required by our Bylaws or otherwise. The Board is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification and will reconsider whether to retain Deloitte & Touche LLP if the stockholders fail to ratify the Audit Committee’s selection. In addition, even if the stockholders ratify the selection of Deloitte & Touche LLP, the Audit Committee may in its discretion appoint a different independent registered public accounting firm at any time during the year if the Audit Committee determines that a change is in the best interests of Sonic.

Fees and Services

For the fiscal years ended December 31, 2004 and 2005, fees for services provided by Deloitte & Touche LLP were as follows:

The Audit Committee considers the provision of these non-audit services to be compatible with maintaining Deloitte & Touche LLP’s independence.

Pre-approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm

The Audit Committee is responsible for pre-approving all services provided by Sonic’s independent registered public accounting firm and pre-approved all of the services provided in 2005. These services may include audit services, audit-related services, tax services and other services. The Audit Committee has delegated its pre-approval authority to its chairman. The chairman in turn reports to the Audit Committee at least quarterly on audit and non-audit services he pre-approved since his last report.

Sonic’s executive compensation program is comprised of two components: annual cash compensation, paid in the form of annual salary and performance-based bonuses, and long-term compensation, paid principally in the form of restricted shares of and options to purchase Sonic’s Class A Common Stock. The Compensation Committee typically reviews and adjusts base salaries and awards of cash bonuses and equity-based compensation in the first quarter of each year.

Annual Cash Compensation

Annual cash compensation for Sonic’s executive officers consists of a base salary and the potential for an annual performance-based cash bonus. The annual cash compensation paid by Sonic to its executive officers during 2005 was targeted to be competitive principally in relation to other automotive retailing companies (such as those included in the Peer Group Index in the performance graph elsewhere herein). The Compensation Committee also considered the compensation of executives of some retailing companies not included in the Peer Group Index because the Compensation Committee considered those other companies to be in relatively comparable industries. Analysis of the competitiveness of annual cash compensation paid by Sonic to its executives was provided to the Compensation Committee during 2005 by an independent consulting firm retained by the Compensation Committee that specializes in executive compensation.

The base salaries of Sonic’s executive officers and adjustments to executive officers’ base salaries are generally based upon a subjective evaluation of the executive’s performance by the Compensation Committee, executive compensation of comparable companies and recommendations submitted to the Compensation Committee by the Chief Executive Officer. The Compensation Committee’s evaluation is based upon non-quantitative factors such as the current responsibilities of each executive officer, the compensation of similarly situated executive officers of comparable companies, the performance of each executive officer during the prior calendar year and adjustments made to the base salaries of certain of the executive officers during the prior calendar year. In March 2005, the base salaries of the executive officers for 2005 were established based on these factors. At that time, the Compensation Committee increased the base salary of Mr. Scott Smith to $900,000. The Compensation Committee did not adjust the base salaries of any executive officers, other than Messrs. Bruton and Scott Smith during the 2005 calendar year.

Each of Sonic’s executive officers participated in the Sonic Automotive, Inc. Incentive Compensation Plan (the “Incentive Plan”) during the 2005 calendar year. In March 2005, the Compensation Committee established objective, performance-based goals and bonus award amounts for each executive officer for the performance period beginning January 1, 2005 and ending December 31, 2005, with annual cash bonuses to be paid as soon as administratively practicable following the Compensation Committee’s determination of the extent to which the specified performance goals were achieved. The Compensation Committee established two categories of performance goals for each of the executive officers, other than Mr. Iuppenlatz: defined earnings per share levels and customer satisfaction performance for Sonic’s dealerships in specified major brands. The Compensation Committee also established a performance goal for Mr. Iuppenlatz of defined earnings per share levels. Mr. Iuppenlatz was also eligible for a discretionary bonus based on a subjective evaluation by the Compensation Committee of his performance as Executive Vice President of Corporate Development. The Compensation Committee delegated to Sonic’s President and Chief Financial Officer the authority to establish objective, position-related performance goals for Mr. Iuppenlatz during 2005 for purposes of this discretionary bonus, with Sonic’s President to report to the Compensation Committee on Mr. Iuppenlatz’s performance against such goals. The Compensation Committee then established bonus award amounts for each of the executive officers for specified levels of achievement of the performance goals, subject to reduction in the event the Compensation Committee determined that subjective or other factors warranted a reduction. Based on Sonic’s performance against the performance-based goals, the Compensation Committee certified that the objective, performance-based criteria had been met. As a result, the Compensation Committee authorized award amounts for each of the executive officers under the Incentive Plan for the specified levels of achievement within those performance categories in the following amounts: $507,000 for B. Scott Smith; $563,333 for Jeffrey C. Rachor and $170,000 for Mark J. Iuppenlatz. In addition, based upon the recommendation of Sonic’s President, the Compensation Committee also awarded Mr. Iuppenlatz a discretionary bonus in the amount of $202,000, which recommendation was based on objective, position-related performance goals established by Sonic’s President and Chief Financial Officer as delegated by the Compensation Committee. The Compensation Committee also determined that the bonuses awarded to the executive officers under the

10

Incentive Plan for 2005 did not sufficiently reward the executives for their respective strong performances on behalf of Sonic during the year. Accordingly, the Compensation Committee awarded supplemental discretionary cash bonuses to the named executive officers in the following amounts: B. Scott Smith, $192,000; Jeffrey C. Rachor, $213,333 and Mark J. Iuppenlatz, $80,000. The Compensation Committee approved payment of the Incentive Plan and supplemental cash bonuses in February 2006.

Long-term Compensation

The Compensation Committee believes that equity-based compensation is the most effective means of aligning the long-term interests of Sonic’s executive officers with those of its stockholders. Sonic’s long-term compensation program is based principally upon awards of restricted shares of and options to purchase Sonic’s Class A Common Stock under the Sonic Automotive, Inc. 1997 Stock Option Plan (the “Stock Option Plan”) and the Sonic Automotive, Inc. 2004 Stock Incentive Plan (the “Stock Incentive Plan”). Awards of stock options or restricted stock (other than to the Chief Executive Officer) are based upon a subjective evaluation of the executive’s performance by the Compensation Committee and recommendations submitted to the Compensation Committee by the Chief Executive Officer. The Compensation Committee’s evaluation considers a number of non-quantitative factors, including the responsibilities of the individual officers for and contribution to Sonic’s operating results (in relation to other recipients of Sonic equity awards), and their expected future contributions. In April 2005, the Compensation Committee awarded options to purchase shares of Sonic’s Class A Common Stock under the Stock Option Plan to the named executive officers (other than the Chief Executive Officer) as follows: options to purchase 75,000 shares to Mr. Scott Smith; options to purchase 75,000 shares to Mr. Rachor; options to purchase 40,000 shares to Mr. Wyatt; and options to purchase 30,000 shares to Mr. Iuppenlatz. In addition, in April 2005, Mr. Iuppenlatz was awarded 12,000 restricted shares of Class A Common Stock pursuant to the Stock Incentive Plan. For additional details concerning the options and restricted stock granted to and held by the executive officers during the 2005 calendar year, see “—Compensation of Executive Officers,” “—Option Grants in 2005” and “—Fiscal Year-End Option Values.”

Deferred Compensation Plan and Other Benefit Plans

Executive officers of Sonic (including the Chief Executive Officer) were also eligible to participate in the Sonic Automotive, Inc. Deferred Compensation Plan (the “Deferred Plan”) during the 2005 calendar year. Under the Deferred Plan, eligible employees could elect to defer a portion of their annual cash compensation, up to a maximum of 40% or $250,000, whichever was lower. Sonic makes cash matching contributions of 20% of the amount deferred by the employee, not to exceed $10,000 per year in matching contributions. Sonic may also make supplemental contributions for eligible employees to make up for the additional matching contributions the employees would have received under Sonic’s 401(k) plan in the absence of legal limitations on the amount of compensation that could be considered under the 401(k) plan (e.g., $210,000 for 2005). Sonic’s contributions generally vest pro rata over a five year period. Participation in the Deferred Plan is offered annually to a select group of our management and highly compensated employees. Contributions by participants in the Deferred Plan, including the executive officers, may be invested in several different investment funds offered by the third-party administrator of the Deferred Plan, with earnings on such amounts determined by the actual market performance of the investment funds selected by the participant.

Executive officers of Sonic (including the Chief Executive Officer) were also eligible in 2005 to participate in various benefit plans similar to those provided to other employees of Sonic. These benefit plans are intended to provide a safety net of coverage against various events, such as death, disability and retirement.

Chief Executive Officer Compensation

The Compensation Committee annually reviews and approves the compensation of Mr. Bruton Smith, Sonic’s Chief Executive Officer. For the 2005 calendar year, Mr. Smith’s annual base salary was increased by the Compensation Committee to $1,100,000. The Compensation Committee’s adjustment of Mr. Smith’s base salary was based upon non-quantitative factors such as the current responsibilities of Mr. Smith, the compensation of similarly situated executive officers of comparable companies, the performance of Mr. Smith during the prior calendar year and adjustments made to the base salaries of certain of the executive officers during the prior calendar year. Mr. Smith’s annual salary is targeted to be competitive principally in relation to other automotive retailing companies (such as those included in the Peer Group Index in the performance graph elsewhere herein). The Compensation Committee also considered the compensation of executives of

11

some retailing companies not included in the Peer Group Index because the Compensation Committee considered those other companies to be in relatively comparable industries. Analysis of the competitiveness of the annual compensation paid to Mr. Smith was provided to the Compensation Committee during 2005 by an independent consulting firm retained by the Compensation Committee that specializes in executive compensation.

The Compensation Committee considers annual stock option and/or restricted share awards to Mr. Smith based upon a subjective evaluation of his performance as Chief Executive Officer. The Compensation Committee’s evaluation is based upon a number of non-quantitative factors, including his responsibility for and contribution to Sonic’s operating results (in relation to other recipients of Sonic equity awards), and his expected future contributions. During the 2005 calendar year, the Compensation Committee awarded Mr. Smith options to purchase 100,000 shares of Sonic’s Class A Common Stock under the Stock Option Plan. For additional details concerning the stock options granted to and held by Mr. Smith during the 2005 calendar year, see “—Option Grants in 2005” and “—Fiscal Year-End Option Values.”

With respect to Mr. Smith’s annual cash bonus for 2005, the Compensation Committee determined that Mr. Smith would again participate in the Incentive Plan for the 2005 calendar year and would have his annual cash bonus determined based upon attainment of objective, performance-based goals established by the Compensation Committee pursuant to the terms of the Incentive Plan. In March 2005, the Compensation Committee established two categories of performance goals for Mr. Smith: defined earnings per share levels and customer satisfaction performance for Sonic’s dealerships in specified major brands. The Compensation Committee then established bonus award amounts for Mr. Smith for specified levels of achievement of the performance goals, subject to reduction in the event the Compensation Committee determined that subjective or other factors warranted a reduction. Based on Sonic’s performance against the performance-based goals, the Compensation Committee certified that the objective, performance-based criteria had been met. As a result, the Compensation Committee authorized an award for Mr. Smith under the Incentive Plan for the specified levels of achievement within those performance categories in the amount of $619,667. The Compensation Committee also awarded a discretionary cash bonus to Mr. Smith in the amount of $234,667. The Compensation Committee approved payment of these awards in February 2006.

Federal Income Tax Considerations

As noted above, the compensation paid to Sonic’s executive officers is based primarily on the performance of Sonic. Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), imposes a limitation on the deductibility of annual compensation in excess of $1 million that is not performance-based. Executive officer compensation attributable to the exercise of stock options granted under the Stock Option Plan and Stock Incentive Plan and annual cash bonuses paid under the Incentive Plan should qualify as fully deductible performance-based compensation. The Compensation Committee currently intends to continue to manage Sonic’s executive compensation program in a manner that will preserve federal income tax deductions. However, the Compensation Committee also must approach executive compensation in a manner which will attract, motivate and retain key personnel whose performance increases the value of Sonic. Accordingly, the Compensation Committee may from time to time exercise its discretion to award compensation that may not be deductible under Section 162(m) of the Code when in its judgment such award would be in the interests of Sonic. The Compensation Committee exercised such discretion in 2005 with respect to the award of supplemental discretionary bonuses to the executive officers as discussed above, a portion of which will not be deductible due to the Code Section 162(m) limitation.

Compensation of Executive Officers

The following table sets forth compensation paid by or on behalf of Sonic to the Chief Executive Officer of Sonic and to its other named executive officers for services rendered during Sonic’s fiscal years ended December 31, 2003, 2004 and 2005:

Summary Compensation Table

Employment Agreements

Sonic has employment agreements (collectively, the “Employment Agreements”) with Messrs. Rachor and Iuppenlatz (collectively, the “Executives”). Under the terms of the Employment Agreements, Sonic will employ the Executives through September 1, 2007, subject to automatic extension for successive one-year periods. The Employment Agreements set forth

13

the basic terms of employment for each Executive, including the initial base salary of $1,000,000 for Mr. Rachor and $500,000 for Mr. Iuppenlatz. The Employment Agreements also provide for an annual performance-based cash bonus and participation in Sonic’s benefit programs. The Employment Agreements provide for initial grants of restricted shares of Class A Common Stock and nonstatutory stock options and eligibility for future grants at the sole discretion of the Compensation Committee of Sonic’s Board of Directors.

The Employment Agreements contain restrictive covenants that prohibit, during periods defined in the Employment Agreements and subject to certain limited exceptions, (i) competing with Sonic, (ii) employing or soliciting Sonic’s employees, (iii) interfering with Sonic’s relationships with its customers or vendors and (iv) disclosing or using in an unauthorized manner any of Sonic’s confidential or proprietary information. The Employment Agreement for Mr. Rachor also provides for severance arrangements in the event Mr. Rachor’s employment is terminated by Sonic other than for cause or by the employee for good reason. Mr. Iuppenlatz’s Employment Agreement provides for severance arrangements in the event his employment is terminated by Sonic other than for cause. Sonic will not be obligated to pay severance if Mr. Rachor or Mr. Iuppenlatz violates the non-competition provisions of his respective Employment Agreement. These restrictive covenants generally apply for a period of two years following the later of the expiration or termination of employment under the Employment Agreement. However, in the event that Mr. Rachor elects to terminate his employment without good reason or he elects not to renew his respective Employment Agreement, Sonic will not be obligated to pay the employee severance and the restrictive covenants will expire one year following the date of termination. In the event that Mr. Iuppenlatz elects to terminate his employment or he elects not to renew his Employment Agreement, the restrictive covenants will expire one year following the date of termination. In either case, the restrictive covenants limit the employee’s competitive activities within any Standard Metropolitan Statistical Area or county in which Sonic has a place of business on the date of expiration or termination of the Employment Agreement.

The employment agreement to which Mr. Wyatt was a party was terminated upon his resignation and no further payments were made in connection with that employment agreement following his resignation. The provisions of his employment agreement that, by their terms, extended beyond the termination of his employment agreement remained in effect. These provisions include, but are not limited to, the restrictive covenants, which will be deemed to commence on April 30, 2006. In connection with Mr. Wyatt’s resignation, Sonic entered into an agreement with him pursuant to which Mr. Wyatt agreed to perform reasonable consulting services to Sonic upon request from September 6, 2005 through April 30, 2006. This agreement provides that Mr. Wyatt receives a monthly fee of $12,500 and reimbursement for pre-approved out-of-pocket business related expenses. The agreement also provides that Mr. Wyatt’s outstanding stock options granted pursuant to the Stock Option Plan continue to vest in accordance with the Stock Option Plan and the terms of the applicable stock option agreements until April 30, 2006. All unvested and unexercised stock options will expire on April 30, 2006.

FirstAmerica Plan

We assumed the FirstAmerica Plan in connection with our acquisition of FirstAmerica Automotive, Inc. (“FAA”). The FirstAmerica Plan has not been approved by Sonic’s stockholders. Upon completion of the acquisition of FAA on December 10, 1999, the FirstAmerica Plan was amended and restated to provide that each outstanding option to purchase a share of FAA Class A Common Stock was converted into the right to purchase 0.32232 shares of Sonic’s Class A Common Stock. The following summary of the FirstAmerica Plan is qualified in its entirety by reference to the FirstAmerica Plan, a copy of which has been filed with the SEC.

The FirstAmerica Plan provides for the grant of incentive stock options to certain employees, within the meaning of Section 422 of the Code, and for the grant of nonstatutory stock options to certain employees, non-employee directors and consultants. Generally, options granted under the FirstAmerica Plan vest over five years, and expire if unexercised within ten years of the date of grant. Options may expire earlier due to termination of employment with the Company. Certain of the options outstanding under the FirstAmerica Plan may provide for partial acceleration upon a change of control.

The total number of shares of Class A Common Stock that were reserved for issuance under the FirstAmerica Plan is 966,960. Options to purchase a total of approximately 14,243 shares of our Class A Common Stock were outstanding under the FirstAmerica Plan as of December 31, 2005. Approximately 693,635 additional shares remain available for future option grants under the FirstAmerica Plan. We have not granted any new options under the FirstAmerica Plan since we assumed it on December 10, 1999 and do not currently intend to grant options to purchase our Class A Common Stock under the FirstAmerica Plan in the future.

Nonqualified Employee Stock Purchase Plan

The Nonqualified Employee Stock Purchase Plan (the “Nonqualified ESPP”) was adopted by the Board of Directors of Sonic on December 11, 1998. The Nonqualified ESPP has not been approved by Sonic’s stockholders. The purpose of the Nonqualified ESPP is to provide employees of certain subsidiaries that are not able to participate in Sonic’s Employee Plan with a similar opportunity to acquire an ownership interest in Sonic. Both the Nonqualified ESPP and the Employee Plan permit eligible employees to purchase shares of Class A Common Stock at a discount from the market price. The terms of the Nonqualified ESPP are substantially similar to the terms of the Employee Plan, which has been approved by Sonic’s stockholders.

The total number of shares of Class A Common Stock that were reserved for issuance under the Nonqualified ESPP is 300,000. Approximately 210,364 additional shares remain available for future option grants under the Nonqualified ESPP.

Employees of participating subsidiaries generally are eligible for the Nonqualified ESPP if they work for Sonic and its subsidiaries on a full-time or part-time basis, are regularly scheduled to work more than twenty hours per week, are customarily employed more than five months in a calendar year and have completed one year of continuous service. Employees who are officers or directors of Sonic or any participating employer are not eligible to participate in the Nonqualified ESPP. In addition, employees who own or hold options to purchase (or who are treated under certain tax rules as owning or holding options to purchase) 5% or more of the total combined voting power or value of all classes of stock of Sonic or any subsidiary also are not eligible to participate in the Nonqualified ESPP.

Options generally are granted under the Nonqualified ESPP as of each January 1 to all eligible employees who elect to participate. The Compensation Committee designates the number of shares of Class A Common Stock that can be purchased under each option, which number will be the same for each option granted on the same date and which also will be the same number of shares available under an option granted on the same date pursuant to the Employee Plan. The options have an exercise price per share equal to the lesser of (i) 85% of the fair market value per share of the Class A Common Stock on the date of grant or (ii) 85% of such fair market value on the date of exercise. No option can be granted which would permit a participant to purchase more than $25,000 worth of stock under the Nonqualified ESPP during the calendar year.

A participant can make contributions to the Nonqualified ESPP by after-tax payroll deduction or direct payment. To the extent that a participant has made contributions to the Nonqualified ESPP, his or her option will be exercised automatically to purchase Class A Common Stock on each exercise date during the calendar year in which the option is granted. The exercise dates generally are the last business day of March, June, September and December on which the NYSE is open for

16

trading. The participant’s accumulated contributions as of each exercise date will be used to purchase whole shares of Class A Common Stock at the applicable option price, limited to the number of shares available for purchase under the option. The exercisability of options may accelerate in the event of a change in control of Sonic.

Options granted under the Nonqualified ESPP expire on the last exercise date of the calendar year in which granted. However, if a participant withdraws from the Nonqualified ESPP or terminates employment, the option may expire earlier.

In the event of certain changes in the capital stock of Sonic due to a reorganization, stock split, stock dividend, merger or other similar event, appropriate adjustments generally will be made to the shares of Class A Common Stock available for issuance under the Nonqualified ESPP, the shares of Class A Common Stock covered by outstanding options and the exercise price per share.

The Board of Directors of Sonic generally can amend, suspend or terminate the Nonqualified ESPP at any time. However, no amendment, suspension or termination may adversely affect the rights of the participant under an outstanding option without the participant’s consent. The Board of Directors suspended the Nonqualified ESPP effective December 31, 2005.

Director Compensation

Each non-employee director receives a $35,000 annual cash retainer payable in quarterly installments. Sonic’s lead independent director and the chairperson of the audit committee receive an additional annual cash retainer of $12,500. The chairperson of the compensation committee receives an additional annual cash retainer of $10,000, and the chairperson of the nominating and corporate governance committee receives an additional annual cash retainer of $7,500. Each non-employee director also receives $2,000 for each board meeting attended in person and $1,000 for each board meeting attended telephonically. In addition, committee members receive the following fees for attending meetings of a committee on which they serve: $2,000 for each audit committee meeting attended in person or telephonically; and $1,500 for each other committee meeting attended in person and $1,000 for each other committee meeting attended telephonically.

Non-employee directors also receive automatic grants of restricted stock during each year of service under the 2005 Formula Plan. The annual grant of restricted stock is made to each eligible non-employee director on the first business day following each annual meeting of Sonic’s stockholders. The number of restricted shares of Class A Common Stock granted to an eligible non-employee director each year will equal $60,000 divided by the average closing sale price of the Class A Common Stock on the NYSE for the twenty trading days immediately prior to the grant date (rounded up to the nearest whole share). Subject to the director’s continued service on Sonic’s Board, the restricted stock will vest in full on the first anniversary of the grant date or, if earlier, the day before the next annual meeting of Sonic’s stockholders following the grant date. If a non-employee director initially becomes a member of Sonic’s Board of Directors during any calendar year, but after the meeting of Sonic’s stockholders for that year, the non-employee director will receive a restricted stock grant upon his or her appointment to the Board with the number of shares determined as described above. Subject to the director’s continued service on Sonic’s Board, the restricted stock will vest in full on the first anniversary of the grant date.

Shares of restricted stock may not be sold, assigned, pledged or otherwise transferred to the extent they remain unvested. A director holding restricted stock will have the right to vote his or her shares of restricted stock and receive dividends (if any), although dividends paid in shares will be considered restricted stock. If a director’s service on the Board terminates for any reason, all shares of restricted stock not vested at the time of such termination are forfeited. Upon either the consummation of a tender or exchange offer that constitutes a “change in control” (as defined in the 2005 Formula Plan) of Sonic or the third business day prior to the effective date of any other “change in control” of Sonic, all outstanding restricted stock generally will become fully vested.

Stockholder Performance Graph

Set forth below is a line graph comparing the cumulative stockholder return on Sonic’s Class A Common Stock against the cumulative total return of each of the Standard and Poor’s 500 Stock Index and a Peer Group Index for the time period commencing December 31, 2000 and ending December 31, 2005. The companies used in the Peer Group Index consist of AutoNation, Group 1 Automotive, United Auto Group, Car Max and Lithia Motors, which are all publicly traded companies known by Sonic to be involved in the automotive retail industry. The graph assumes that $100 was invested on December 31, 2000 in each of Sonic’s Class A Common Stock, the Standard & Poor’s 500 Stock Index and the Peer Group Index companies and that all dividends were reinvested.

CERTAIN TRANSACTIONS

Registration Rights Agreement

When Sonic acquired Town & Country Ford, Lone Star Ford, Fort Mill Ford, Town & Country Toyota and Frontier Oldsmobile-Cadillac in 1997, Sonic signed a Registration Rights Agreement dated as of June 30, 1997 with SFC, O. Bruton Smith, B. Scott Smith and William S. Egan (collectively, the “Class B Registration Rights Holders”). SFC currently owns 8,881,250 shares of Class B Common Stock; Bruton Smith, 2,171,250 shares; and Scott Smith, 976,875 shares; all of which are covered by the Registration Rights Agreement. Egan Group, LLC, an assignee of Mr. Egan, also owns certain shares of Class A Common Stock to which the Registration Rights Agreement applies. If, among other things provided in Sonic’s Charter, offers and sales of shares Class B Common Stock are registered with the SEC, then such shares will automatically convert into a like number of shares of Class A Common Stock.

The Class B Registration Rights Holders have certain limited piggyback registration rights under the Registration Rights Agreement. These rights permit them to have their shares of Sonic’s Common Stock included in any Sonic registration statement registering Class A Common Stock, except for registrations on Form S-4, relating to exchange offers and certain other transactions, and Form S-8, relating to employee stock compensation plans. The Registration Rights Agreement expires in November 2007. SFC is controlled by O. Bruton Smith.

The SFC Pledge

Before Sonic’s acquisition of FirstAmerica in December 1999, Bruton Smith guaranteed the obligations of FirstAmerica under FirstAmerica’s new acquisition line of credit with Ford Motor Credit. FirstAmerica obtained this new financing to enable it to complete its then pending acquisitions. The borrowing limit under this credit facility was approximately $138 million prior to FirstAmerica’s acquisition by Sonic. Mr. Smith guaranteed approximately $107 million of this amount, which guarantee was secured by a pledge of 5 million shares of SMI Common Stock owned by SFC. Sonic assumed FirstAmerica’s obligations to Ford Motor Credit under the Revolving Facility when it acquired FirstAmerica. In connection with the refinancing and replacement of the secured lending facility (the “Revolving Facility”) with a new secured lending facility between Sonic, Ford Motor Credit Company (“Ford Motor Credit”) and Chrysler Financial Company, LLC in

18

August 2000 (as amended, the “Revolving Facility”), Ford Motor Credit released Mr. Smith from his secured guarantee under the replaced Revolving Facility. However, the lenders under the Revolving Facility required that the SFC Pledge remain in place, and it continually secured Sonic’s obligations under the Revolving Facility through February 17, 2006, when the Revolving Facility was terminated. SFC made the same pledge as collateral security for Sonic’s new secured syndicated credit facility entered into on February 17, 2006, which provides up to $1.2 billion in borrowing availability for Sonic for new vehicle inventory floor plan financing, used vehicle inventory floor plan financing and for working capital and general corporate purposes, including acquisitions and capital expenditures.

Other Transactions

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires Sonic’s directors, certain officers and persons who own more than 10% of Sonic’s Voting Stock to file reports on ownership and changes in ownership with the SEC. Additionally, SEC regulations require that Sonic identify in its proxy statements any individuals for whom one of the referenced reports was not filed on a timely basis during the most recent fiscal year or prior fiscal years. To Sonic’s knowledge, based solely on review of reports furnished to it, all Section 16(a) filing requirements applicable to its directors, officers and more than 10% beneficial owners were complied with on a timely basis, except for one late Form 4 filing by Greg Young to report an exercise of options and open market sale of the acquired shares.

APPENDIX A

CATEGORICAL STANDARDS FOR DETERMINATION OF DIRECTOR INDEPENDENCE

It is the policy of Sonic Automotive, Inc. (the “Company”) to have a majority of independent directors. No director qualifies as independent under the New York Stock Exchange (“NYSE”) corporate governance rules unless the board of directors affirmatively determines that the director has no material relationship with the Company. The NYSE’s corporate governance rules include several “bright line” tests for director independence. No director who has a direct or indirect relationship that is covered by one of those tests qualifies as an independent director. To assist the board of directors in making determinations of independence about relationships individual directors may have that are not covered by one of those “bright line” tests, the board of directors has adopted categorical standards for director independence that are set forth below.

* * * *

The Board of Directors has determined that the following relationships with the Company, either directly or indirectly, will not be considered material relationships for purposes of determining whether a director is independent:

For purposes of this categorical standard, contributions made to any charitable organization pursuant to a matching gift program maintained by the Company or by its subsidiaries or by any foundation sponsored by or associated with the Company or its subsidiaries shall not be included in calculating the materiality threshold set forth above.

CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

AMENDED AND RESTATED FEBRUARY 9, 2006

The Audit Committee is appointed by the Board of Directors to assist the Board in fulfilling its oversight responsibilities relating to the Company’s accounting policies, reporting policies, internal controls, compliance with legal and regulatory requirements, and the integrity of the Company’s financial reports. The Audit Committee’s primary duties and responsibilities are to:

The Audit Committee has the authority to conduct any investigation appropriate to fulfilling its responsibilities, and it has direct access to the independent auditors as well as anyone in the organization. The Audit Committee has the ability to retain, at the Company’s expense, special legal, accounting, or other consultants or experts it deems necessary in the performance of its duties.

The Audit Committee shall consist of three or more directors, each of whom is “independent” (as defined by applicable New York Stock Exchange (“NYSE”) and Securities and Exchange Commission (“SEC”) rules in effect from time to time). Each Audit Committee member must also be “financially literate” (as such qualification is interpreted by the Board in its business judgment) or must become financially literate within a reasonable period of time after his or her appointment to the Audit Committee. At least one member of the Audit Committee must have accounting or related financial management expertise (as the Board interprets such qualification in its business judgment), and at least one member shall be an “audit committee financial expert” (as determined under the rules promulgated by the SEC).

Audit Committee members, and the Chairman of the Audit Committee, shall be appointed by the Board on the recommendation of the Nominating and Corporate Governance Committee. The Chairman shall meet the experience requirements of the NYSE.

No Audit Committee member may receive compensation, directly or indirectly, from the Company other than director’s fees. As used in this Audit Committee Charter, the term “director’s fees” includes normal fees (including equity-based awards) and reimbursement of expenses paid to directors for service on the Board of Directors or Committees thereof, or attendance at meetings thereof, which fees have previously been approved by the Board of Directors. In addition, no Audit Committee member may simultaneously serve on the Audit Committee of more than two (2) other public companies unless the Board of Directors shall affirmatively determine that such simultaneous service would not impair the ability of such member to effectively serve on the Company’s Audit Committee and the Company affirmatively discloses such determination in the Company’s annual proxy statement.

B-1

The Audit Committee shall meet as often as it deems necessary and appropriate to fulfill its purpose and responsibilities, but no less regularly than necessary to review the financial results of the Company for any period in which financial statements or information are prepared and disseminated to stockholders.

One-third of the members, but not less than two, will constitute a quorum of the Audit Committee, and a majority of the members present at any meeting at which a quorum is present may act on behalf of the Audit Committee. The Audit Committee may meet by telephone or video conference, and may take action by unanimous written consent of its members.

The Audit Committee shall meet separately in executive session at least quarterly with management, with the director of the internal auditing department, with the independent auditors, and as a committee to discuss any matters that the Audit Committee or any of these groups believe should be discussed.

1. The independent auditors are ultimately accountable to the Audit Committee. The Audit Committee shall review the independence and oversee the performance of the auditors and shall have the sole authority to appoint the independent auditors, or approve any discharge of auditors when circumstances warrant.

2. Review and reassess the adequacy of this Charter at least annually. Submit the charter to the Board of Directors for approval and have the document published at least every three years in accordance with SEC regulations.

3. Meet to review and discuss with management and the independent auditors the Company’s annual audited financial statements, including disclosures in the Annual Report on Form 10-K under “Management’s Discussion and Analysis of Financial Condition and Results of Operation” and Management’s assertion regarding the effectiveness of the Company’s internal controls over financial reporting, prior to filing or distribution. Review should include discussion with management and the independent auditors of significant issues regarding accounting principles, practices, and judgments made in connection with the preparation of the Company’s financial statements, including an analysis of the effect on the financial statements of applying alternative methods under generally accepted accounting principles and a description of any transactions as to which management obtained letters prepared in accordance with AICPA Statement on Auditing Standards No. 50. Recommend, if appropriate, to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K.

4. Meet to review and discuss with management and the independent auditors the Company’s quarterly financial results prior to the release of earnings and the Company’s quarterly financial statements (including the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operation”) prior to filing or distribution, including the results of the independent auditors’ review of the quarterly financial statements. Discuss any significant changes to the Company’s accounting principles and any items required to be communicated by the independent auditors in accordance with AICPA Statement of Auditing Standards No. 61 (see Item 11 below). The Chairman of the Audit Committee may represent the entire Audit Committee for purposes of this review.

5. Discuss earnings press releases, as well as financial information and earnings guidance provided to analysts and rating agencies.

6. In consultation with management, the independent auditors, and the internal auditors, review the adequacy and effectiveness of the Company’s internal accounting and financial controls.

8. Review significant findings prepared by the independent auditors together with management’s responses.

9. Review the appropriateness of the Company’s accounting policies, and the effect of regulatory and accounting initiatives as well as any off-balance sheet structures as they apply to the Company’s financial statements.

10. The Audit Committee shall review and pre-approve the audit services to be provided to the Corporation by the independent auditors, and shall review and approve the fees to be paid to the independent auditors for such audit services.

B-2

The Audit Committee shall also review and pre-approve the retention of the independent auditors for any non-audit services to be provided to the Corporation, and shall review and approve the fees to be paid to the independent auditors for such non-audit services. The Audit Committee may delegate to one or more of its members the authority to pre-approve audit and non-audit services, and to approve the fees to be paid for such audit and non-audit services. The decision of any member of the Audit Committee to whom authority is delegated pursuant to the preceding sentence shall be presented to the full Audit Committee at its next meeting.

11. On at least an annual basis, the Audit Committee will obtain and review a report by the independent auditors on: (a) the auditing firm’s internal quality-control procedures; (b) any material issues raised by the auditing firm’s most recent internal quality-control review, or peer review, of the auditing firm, or by any inquiry or investigation by governmental or professional authorities, within the preceding five (5) years, respecting one or more independent audits carried out by the auditing firm, and any steps taken to deal with any such issues; and (c) all relationships between the independent auditing firm and the Company. The Audit Committee should discuss with the independent auditors any significant issues regarding the auditors’ qualifications, performance or independence. As to the issue of independence, the Audit Committee shall consider whether the provision of non-audit services is compatible with maintaining the auditors’ independence and take appropriate action to satisfy itself of the independence of the auditors. The Audit Committee shall present its conclusions with respect to the independent auditors to the full Board of Directors.

12. Annually review the independent auditors’ audit plan—discuss scope, staffing, locations, reliance upon management, and internal audit and general audit approach. Annually review the experience and qualifications of the lead partner and other senior members of the independent auditors’ team, and determine that all partner rotation requirements, as promulgated by applicable rules and regulations, are observed. The Committee will also consider whether there should be rotation of the independent auditors.

13. Prior to releasing the year-end earnings, discuss the results of the audit with the independent auditors. Discuss certain matters required to be communicated to audit committees in accordance with AICPA Statement of Auditing Standards No. 61, as amended by SAS No. 84 and SAS No. 90.

28. Maintain minutes of meetings and circulate such minutes to the entire Board of Directors.
