                               PART III--NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the
transition report or portion thereof, could not be filed within the prescribed
time period.

Credit Acceptance Corporation (the "Company") is unable to timely file its
Quarterly Report on Form 10-Q for the quarter ended September 30, 2005 (the
"Form 10-Q") due to the following reasons. On April 1, 2005, the Company's now
former independent registered public accounting firm, Deloitte & Touche LLP
("Deloitte"), informed the Company that their National Office was reviewing the
Company's accounting for loans. The Company viewed this review as a part of
Deloitte's quality control process prior to the Company releasing its Form 10-K
due to the Company's restatement related to income tax accounting. On April 8,
2005, Deloitte informed the Company that it believed the Company should not
account for loans as an originator of loans to consumers but should instead
account for its loans as a lender to its dealer-partners. The Company had
accounted for its loans to consumers as a loan originator since 1992, and
believed such accounting was in accordance with GAAP. As a result, on April 26,
2005, the Company submitted a letter to the staff of the Office of the Chief
Accountant of the Securities and Exchange Commission (the "SEC") requesting
guidance from the SEC related to the accounting methodology the Company used for
its loan portfolio to determine if it could continue with the accounting
treatment it had followed since going public in 1992 or whether it should adopt
an alternative methodology proposed by Deloitte. On June 24, 2005, the SEC
informed the Company that the Company's method for recording loans should be
changed to that of a lender to dealer-partners, rather than an originator of
consumer loans. As a result of this determination, the Company is required to
restate its previously reported financial results. The Company cannot predict
what impact this change will have on its financial statements. Until the process
of restating its prior period financial results has been completed, the Company
will be unable to finalize its financial statements for the period ended
September 30, 2005 and prepare the related disclosures for the Form 10-Q.

                           PART IV--OTHER INFORMATION

(1)  Name and telephone number of person to contact in regard to this 

     Douglas W. Busk, Treasurer           248           353 - 2700  Ext. 4432
               (Name)                 (Area Code)        (Telephone Number)

(2)  Have all other periodic reports required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months or for such shorter period that the
     registrant was required to file such report(s) been filed? If the answer is
     no, identify report(s).

     [  ] Yes [X] No    The Company has not filed its Annual Report on Form 10-K
     for the year ended December 31, 2004, its Quarterly Report on Form 10-Q for
     the quarterly period ended March 31, 2005, or its Quarterly Report on Form
     10-Q for the quarterly period ended June 30, 2005.

(3)  Is it anticipated that any significant change in results of operations from
     the corresponding period for the last fiscal year will be reflected by the
     earnings statements to be included in the subject report or portion

     [X] Yes [  ] No

     If so: attach an explanation of the anticipated change, both narratively
     and quantitatively, and if appropriate, state the reasons why a reasonable
     estimate of the results cannot be made.

     As a result of the matters noted in Part III above, the Company is not in a
     position to provide a reasonable estimate of any anticipated significant
     changes in results of operations from the quarter and nine months ended
     September 30, 2004 to the quarter and nine months ended September 30, 2005
     that may be reflected in the earnings statements to be included in the
     Quarterly Report on Form 10-Q for the quarterly period ended September 30,
