              CREDIT ACCEPTANCE CORPORATION ANNOUNCES FINAL RESULTS
                   OF ITS MODIFIED DUTCH AUCTION TENDER OFFER

         SOUTHFIELD, MICHIGAN -- SEPTEMBER 15, 2004 -- CREDIT ACCEPTANCE
CORPORATION (NASDAQ: CACC) today announced the final results of its modified
dutch auction tender offer, which expired at 5:00 p.m. Eastern Standard Time, on
September 9, 2004. Credit Acceptance commenced the tender offer on August 11,
2004 to purchase up to 3,000,000 shares of its common stock at a price between
$14.00 and $20.00 per share, net to the seller in cash, without interest. Based
on the final count by Computershare Trust Company of New York, the depositary
for the tender offer, 2,673,073 shares of common stock were properly tendered
and not withdrawn at prices between $14.00 and $20.00 per share. The final count
of shares purchased is less than the amount communicated in the Company's
preliminary announcement on September 10, 2004, by 73,655 shares, reflecting
failed delivery of these shares prior to 5:00 p.m. on September 14, 2004. Credit
Acceptance has purchased all of the 2,673,073 tendered shares of its common
stock at a price of $20.00 per share, at a total cost of approximately $53.5
million. The Company financed the purchase of its securities in the tender offer
by borrowing under its $135 million revolving credit facility.

         As a result of the completion of the tender offer, Credit Acceptance
has approximately 36.6 million shares of common stock outstanding. Georgeson
Shareholder Communications, Inc. was the information agent for the offer.

DESCRIPTION OF CREDIT ACCEPTANCE CORPORATION

Since 1972, Credit Acceptance has provided auto loans to consumers, regardless
of their credit history. Our product is offered through a nationwide network of
automobile dealers who benefit by selling vehicles to consumers who otherwise
could not obtain financing, by repeat and referral sales generated by these same
customers, and from sales to customers responding to advertisements for our
product, but who actually end up qualifying for traditional financing.

Without our product, consumers are often unable to purchase a vehicle or they
purchase an unreliable one and are not provided the opportunity to improve their
credit standing. As we report to the three national credit reporting agencies, a
significant number of our customers improve their lives by improving their
credit score and move on to more traditional sources of financing. Credit
Acceptance is publicly traded on the NASDAQ National Market under the symbol
CACC. For more information, visit www.creditacceptance.com.
