AutoNation 401k Plan - Offer to Purchase for Cash

We previously sent you an Important Notice, informing you that AutoNation, Inc
is offering to purchase, for $23 per share in cash, up to 50,000,000 shares of
its common stock (Ticker Symbol-AN).

This notice is to remind you that:

TO TENDER YOUR SHARES held in the AutoNation 401(k) Plan (the "Plan"), you must
call us at (877) 744-4015 by 2 p.m., New York City time, on April 11, 2006

TO NOT TENDER YOUR SHARES held in the Plan, you must call us at (877) 744-4015
by 2 p.m., New York City time, on April 11, 2006.

If you choose to tender your shares, and such shares are sold, there will be a
cash payment made to your plan account, invested in the Merrill Lynch Retirement
Preservation Trust until you give specific investment direction. As with the
sale of other investments in your Plan account, the sale of any tendered shares
will not be a taxable event. Your tender election does not include any future
shares contributed to your account. If more shares are contributed, you must
call us again to instruct us to tender or not tender those shares. If you choose
to change an election you have made, you must call us no later than 2:00 p.m.,
New York City time, on April 11, 2006. If you fail to make an election, the
AutoNation Employee Benefits Committee (the "EBC") will decide whether or not to
tender some or all of your shares. If all tendered shares exceed the amount to
be acquired, shares will be accepted on a pro-rata basis.

The terms and conditions of the offer are described in detail in the Offer to
Purchase and related Letter of Transmittal and further summarized in the
Important Notice, all of which were previously forwarded to you. You should read
these documents carefully before deciding whether or not to tender your shares.
AutoNation's Board of Directors has approved the making of the offer. However,
neither AutoNation or its Board, the Trustee or the EBC is making a
recommendation as to whether or not you should instruct us as Trustee to tender
any of your Plan shares. You are advised to consult your tax advisor concerning
your decision to participate in the offer.
