| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation – The accompanying unaudited condensed consolidated financial statements of Sonic Automotive, Inc. and its wholly owned subsidiaries (“Sonic,” the “Company,” “we,” “us” or “our”) for the three and nine months ended September 30, 2022 and 2021 are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States (the “U.S.”) (“GAAP”) for interim financial information and applicable rules and regulations of the U.S. Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of management, all material normal, recurring adjustments necessary to fairly state the financial position, results of operations and cash flows for the periods presented. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in Sonic’s Annual Report on Form 10-K for the year ended December 31, 2021. |
| Principles of Consolidation | Principles of Consolidation – All of our dealership and non-dealership subsidiaries are wholly owned and consolidated in the accompanying unaudited condensed consolidated financial statements, except for one 50%-owned dealership that is accounted for under the equity method. All material intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements. |
| Per Share Data and Stockholders' Equity | Earnings Per Share – The calculation of diluted earnings per share considers the potential dilutive effect of restricted stock units, restricted stock awards and stock options granted under Sonic’s stock compensation plans (and any non-forfeitable dividends paid on such awards). |
