ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

      On March 24, 2005, Credit Acceptance Corporation (the "Company") issued a
press release announcing its financial results for the three months and year
ended December 31, 2004. The press release, dated March 24, 2004, is attached as
Exhibit 99.1 to this Form 8-K and incorporated herein by reference.

      The financial information included in the press release includes a
presentation of net income excluding certain items, in addition to the
presentation of the Company's reported net income. The Company believes this
information is helpful to investors in measuring the performance of the
business, in that excluding the impact of certain items more accurately reflects
the financial performance of the business and allows shareholders to better
compare results between periods and make more informed assumptions about future
results.

      The financial information included in the press release also includes an
adjusted return on capital analysis, which provides an additional perspective on
the financial performance of the Company. The Company believes this information
provides a useful measurement of how effectively the Company is utilizing its
capital.

      Finally, the financial information included in the press release includes
a presentation of adjusted economic profit. Management uses adjusted economic
profit to assess the Company's performance and the amount of value created for
shareholders as well as to make capital allocation decisions. The Company
believes this information is important to shareholders because it allows
shareholders to compare the returns earned by the Company investing capital in
its business with the return they could expect if the Company returned capital
to shareholders and they invested in other securities.
