Dear Mr. Lentz:

Reference is made to that certain letter agreement (the “Consent Agreement”), dated as of January 28, 2009, as extended by that certain extension agreement (the “Extension Agreement”), dated November 23, 2009, by and among Toyota Motor Sales, U.S.A., Inc. (“Toyota”), AutoNation, Inc. (“AutoNation”), ESL Investments, Inc. and its investment affiliates set forth on Exhibit A to the Consent Agreement and such other investment affiliates of ESL Investments, Inc. or individuals that may be added as parties to the Consent Agreement from time to time pursuant to paragraph 9 of the Consent Agreement. Capitalized terms used but not defined in this letter agreement shall have the meanings ascribed thereto in the Consent Agreement.

Each of the parties hereto hereby agrees that paragraph 8 of the Consent Agreement shall be amended by adding the following language at the end of the last sentence of paragraph 8:

; provided, however, that if at any time after ESL has Owned in excess of fifty percent (50%) of the outstanding Common Stock, (i) the exercise of options to purchase Common Stock and/or (ii) the issuance or vesting of restricted shares of Common Stock causes ESL to no longer Own in excess of fifty percent (50%) of the then outstanding Common Stock, then this letter agreement, and Toyota’s waiver and consent hereunder, shall continue to be in effect until any subsequent disposition of Common Stock by ESL during the time when ESL’s Ownership is not in excess of fifty percent (50%) of the then outstanding Common Stock as a result of such exercise, issuance or vesting.
