Ladies and Gentlemen:

     The undersigned hereby tenders the above described shares to Credit
Acceptance Corporation, a Michigan corporation ("CA"), at the price per share
indicated below, net to the seller in cash, without interest, upon the terms and
subject to the conditions set forth in the Offer to Purchase and the related
Letter of Transmittal (which together constitute the "Offer"), receipt of which
are hereby acknowledged.

                                     BOX A

               SHARES TENDERED AT PRICE DETERMINED BY SHAREHOLDER
                (SEE INSTRUCTION 5 OF THE LETTER OF TRANSMITTAL)

     By checking one of the boxes below instead of the box under Box B, "Shares
Tendered at Price Determined Under the Tender Offer," the undersigned hereby
tenders shares at the price checked. This action could result in none of the
shares being purchased if the purchase price determined by CA for the shares is
less than the price checked below. A shareholder who desires to tender shares at
more than one price must complete a separate Letter of Transmittal for each
price at which shares are tendered. The same shares cannot be tendered, unless
previously properly withdrawn as provided in Section 4 of the Offer to Purchase,
at more than one price.

PRICE (IN DOLLARS) PER SHARE AT WHICH SHARES ARE BEING TENDERED (CHECK THE
APPROPRIATE BOX TO INDICATE THE TENDER PRICE, NOT TO BE LESS THAN $28.00 AND NOT
TO EXCEED $31.50

<Table>
                                                    
[ ] $28.00      [ ] $29.00      [ ] $30.00      [ ] $31.00
[ ] $28.50      [ ] $29.50      [ ] $30.50      [ ] $31.50
</Table>

     Check the appropriate box above or, alternatively, check the box below
under Box B, "Shares Tendered at Prices Determined Under the Tender Offer."
Unless you check the box under Box B, if you do not check one and only one of
the boxes above, you will not have validly tendered your shares.

                                     BOX B

           SHARES TENDERED AT PRICE DETERMINED UNDER THE TENDER OFFER
                (SEE INSTRUCTION 5 OF THE LETTER OF TRANSMITTAL)

[ ] The undersigned wants to maximize the chance of having CA purchase all of
    the shares the undersigned is tendering (subject to the possibility of
    proration). Accordingly, by checking this box instead of one of the boxes in
    Box A, the undersigned hereby tenders shares at, and is willing to accept,
    the purchase price determined by CA in accordance with the terms of the
    Offer. I understand this action will have the same effect as if I selected
    the minimum price of $28.00 per share.

     YOU WILL NOT HAVE VALIDLY TENDERED YOUR SHARES IF MORE THAN ONE BOX IS
CHECKED OR IF NO BOX IS CHECKED.

                                        2


                               CONDITIONAL TENDER
                (SEE INSTRUCTION 6 TO THE LETTER OF TRANSMITTAL)

     A shareholder may tender shares subject to the condition that a specified
minimum number of the shareholder's shares tendered pursuant to this Letter of
Transmittal must be purchased if any shares tendered are purchased, all as
described in the Offer to Purchase, particularly in Section 6 thereof. Unless
the minimum number of shares indicated below is purchased by CA in the Offer,
none of the shares tendered by such shareholder will be purchased. It is the
responsibility of the shareholder to calculate the minimum number of shares that
must be purchased if any are purchased, and CA urges shareholders to consult
their own tax advisor before completing this section. Unless this box has been
checked and a minimum specified, the tender will be deemed unconditional.

     [ ] Minimum number of shares that must be purchased, if any are
         purchased: ______ shares.

If, because of proration, the minimum number of shares designated will not be
purchased, CA may accept conditional tenders by random lot, if necessary.
However, to be eligible for purchase by random lot, the tendering shareholder
must have tendered all of his or her shares and checked the box below.

     [ ] The tendered shares represent all shares held by the undersigned.

                                    ODD LOTS
                (SEE INSTRUCTION 9 IN THE LETTER OF TRANSMITTAL)

     To be completed only if shares are being tendered by or on behalf of a
person owning beneficially or of record an aggregate of fewer than 100 shares.

     The undersigned either (CHECK ONE BOX):

     [ ] is the beneficial or of record an aggregate of fewer than 100 shares
         and is tendering all of those shares; or

     [ ] is a broker, dealer, commercial bank, trust company or other nominee
         that: (a) is tendering, for the beneficial owner(s) thereof, shares
         with respect to which it is the record owner; and (b) believes, based
         upon representations made to it by such beneficial owner(s), that each
         such person is the beneficial owner of an aggregate of fewer than 100
         shares and is tendering all of such shares.

                                        3


     In addition, the undersigned is tendering shares either (CHECK ONE BOX):

     [ ] at the price per share indicated in Box A above under "Shares Tendered
         at Price Determined By Shareholder;" or

     [ ] at the purchase price, as the same shall be determined by CA in
         accordance with the terms of the Offer (persons checking this box
         should check Box B on page 2).
