ITEM 8.01.  OTHER EVENTS.

         As previously announced, Credit Acceptance Corporation (the "Company")
was unable to timely file its Annual Report on Form 10-K for the year ended
December 31, 2004. As a result, the Company is not in compliance with certain
covenants in its Sale and Servicing Agreement, dated August 25, 2004, among the
Company, Credit Acceptance Auto Dealer Loan Trust 2004-1, Credit Acceptance
Funding LLC 2004-1 ("Funding"), JPMorgan Chase Bank, N.A., and Systems &
Services Technologies, Inc., as amended (the "Sale and Servicing Agreement"),
and in the agreements related thereto (together with the Sale and Servicing
Agreement, the "Basic Documents").

         On April 26, 2005, the Company, Funding, and Radian Asset Assurance
Inc., as the Controlling Party under the Basic Documents, executed a waiver
whereby the Controlling Party extended the time for the required delivery of the
Company's audited financial statements to May 31, 2005 and waived the defaults
under the Basic Documents resulting from the Company's ongoing discussions
concerning its accounting policies with Deloitte & Touche LLP and the Company's
resulting inability to timely file its Form 10-K and certain related matters.
The waiver expires on May 31, 2005.

         The Company is in the process of obtaining SEC guidance as to the
proper accounting methodology in connection with how it accounts for loans.
There can be no assurance as to the length of time necessary to complete this
process, and the Company believes it is unlikely to be completed prior to May
31, 2005. If the Company is not able to determine the appropriate accounting
policies for loans and file its Form 10-K prior to such date, it intends to seek
an extension of the waiver from the Controlling Party.





CAUTIONARY STATEMENT REGARDING FORWARD LOOKING INFORMATION

Certain statements in this release that are not historical facts, such as those
using terms like "believes," "expects," "anticipates," "assumptions,"
"forecasts," "estimates" and those regarding the Company's future results, plans
and objectives, are "forward-looking statements" within the meaning of the
federal securities laws. These forward-looking statements represent the
Company's outlook only as of the date of this release. While the Company
believes that its forward-looking statements are reasonable, actual results
could differ materially since the statements are based on current expectations,
which are subject to risks and uncertainties. Factors that might cause such a
difference include the following:

         - the Company's potential inability to accurately forecast and estimate
           the amount and timing of future collections,
         - increased competition from traditional financing sources and from
           non-traditional lenders, 
         - the unavailability of funding at competitive rates of interest, 
         - the Company's potential inability to continue to obtain third party
           financing on favorable terms, 
         - the Company's potential inability to generate sufficient cash flow to
           service its debt and fund its future operations,
         - adverse changes in applicable laws and regulations, 
         - adverse changes in economic conditions, 
         - adverse changes in the automobile or finance industries or in the 
           non-prime consumer finance market, 
         - the Company's potential inability to maintain or increase the volume
           of automobile loans, 
         - an increase in the amount or severity of litigation against the 
           Company, 
         - the loss of key management personnel or the inability to hire 
           qualified personnel, 
         - the effect of terrorist attacks and potential attacks, and 
         - various other factors discussed in the Company's reports filed with 
           the Securities and Exchange Commission.

Other factors not currently anticipated by management may also materially and
adversely affect the Company's results of operations. The Company does not
undertake, and expressly disclaims any obligation, to update or alter its
statements whether as a result of new information, future events or otherwise,
except as required by applicable law.
