1. WHY IS IT WHEN I DIVIDE INTEREST EXPENSE ON YOUR FOURTH QUARTER AND 2006
EARNINGS PRESS RELEASE DATED 2/12/07 BY AVERAGE DEBT, THE PRE-TAX RATE IS
APPROXIMATELY 9% (8.98% FOR THE YEAR AND 9.03% FOR THE QUARTER)? THIS VARIES
FROM YOUR MOST RECENTLY FILED 10-Q WHERE UNDER THE DEBT SECTION IT MENTIONS THAT
YOUR ANNUALIZED COST OF YOUR VARIOUS DEBT INSTRUMENTS RANGE FROM AS LOW AS 5.35%
ON YOUR MORTGAGE NOTE TO AS HIGH AS 7.6% ON ONE OF THE SECURED FINANCINGS?

The variance between your calculation and what we disclosed in the third quarter
10-Q is the impact of fixed fees. Your calculation, interest expense divided by
average debt, looks at the total annualized cost of debt, which includes the
actual interest rates on the debt obligations as well as fixed fees such as
underwriter's fees, insurance premiums and commitment fees. The interest rates
disclosed in our SEC filings for our line of credit and warehouse line of credit
exclude the impact of fixed fees.

For the three months and year ended December 31, 2006 the annualized cost of
debt was as follows:




                                                THREE MONTHS ENDED     YEAR ENDED
                                                    12/31/2006         12/31/2006
                                                ------------------     ----------
                                                                 
ACTUAL EXPENSES

Interest Expense ($) .........................        $  5,647         $ 15,033

Fixed Fees ($) ...............................           2,612            8,297

         Total ...............................        $  8,259         $ 23,330


Average Debt .................................        $365,708         $259,802

ANNUALIZED ALL-IN COST OF DEBT

Interest Expense (%) .........................            6.18%            5.79%

Fixed Fees (%) ...............................            2.86%            3.19%

         Total ...............................            9.03%            8.98%



As you can see the impact of fixed fees adds approximately 3% to our annualized
cost of debt for both the three months and year ended December 31, 2006.


2. HOW MUCH OF THE PRICING CHANGES YOU IMPLEMENTED DURING THE 3RD QUARTER OF
2006 EFFECT THE ADJUSTED RETURN ON CAPITAL OF 14.1% THAT YOU REPORTED? YOU
MENTION THAT 90 OF THE 100 BASIS DECLINE IN THE ADJUSTED RETURN ON CAPITAL FROM
THE 4TH QUARTER OF 05 TO THE 4TH QUARTER OF 06 WAS DUE TO ITEMS OTHER THAN THE
PRICE CHANGES. DOES THIS MEAN THE PRICE CHANGES ONLY IMPACTED THE 4TH QUARTER
ADJUSTED RETURN ON CAPITAL BY 10 BASIS POINTS? IN OTHER WORDS, OF THE 150 BASIS
POINTS REDUCTION YOU EXPECT IN ADJUSTED RETURN ON CAPITAL DUE TO THE PRICE
CHANGES AND LICENSE FEE CHANGE, ONLY 10 BASIS POINTS OF IT HAS BEEN REFLECTED IN
THE 4TH QUARTER OF 2006. THEREFORE, ASSUMING



ALL ELSE EQUAL, IS THE GOING FORWARD ADJUSTED RETURN ON CAPITAL EXPECTED TO BE
14.1% LESS 1.4% OR 12.7%?

It is fair to say the impact of our pricing changes on the fourth quarter
reported financial results was very small and that most of the 150 basis point
reduction will be reflected in future periods. Saying the impact was 10 basis
points so far, and that it will be 140 basis points going forward would imply a
greater degree of precision than we feel comfortable with. In fact, this would
be a good time to remind shareholders that, although we have put a priority on
clearly understanding the profitability of every loan we originate, our
profitability models involve substantial estimates, including estimates of the
amount and timing of collection rates, the amount and timing of dealer holdbacks
and estimates of how expense levels will change in the future based on the size,
term and volume of business we originate. Because we understand that our returns
cannot be predicted with exacting precision, we maintain a conservative capital
structure and target returns on capital that are appropriate given the risk of
our business model.

With all that said, using 12.7% as your future return on capital assumption is
not unreasonable based on what we know today.


3. YOU STATED THAT COLLECTIONS IN 2006 GENERALLY EXCEEDED THE COMPANY'S
EXPECTATIONS AT 12/31/05. GIVEN THAT YOUR FORECASTED COLLECTION % HAS FALLEN BY
..5% AND 1.2% FOR 2005 AND 2006, RESPECTIVELY WHEN COMPARING WHAT YOU EXPECTED AT
9/30/06 TO 12/31/06, HAVE YOUR 4TH QUARTER COLLECTIONS FALLEN SHORT OF YOUR
EXPECTATIONS? IF SO, IS THAT WHAT IS CAUSING YOU TO ESTIMATE THAT THE PRICING
CHANGES YOU MADE IN Q3 WILL REDUCE THE ADJUSTED RETURN ON CAPITAL BY AN
ADDITIONAL 25 BASIS POINTS?

It is accurate to say that our full year collection results generally exceeded
our expectations at the start of the year and that fourth quarter collection
results were less than our expectations at the start of the fourth quarter. The
amounts are quantified in the table so we won't elaborate further on the
magnitude of the variance.

With respect to pricing changes, we offer the following clarification: The 125
basis point reduction in our estimated return on capital is related to the Q3
2006 pricing change only and does not include the impact of the collection
variance.


4. WHY HAS RESTRICTED CASH ON THE BALANCE SHEET MORE THAN TRIPLED IN 2006 TO
$45.6M? WHAT IS THE INTEREST RATE EARNED ON THE RESTRICTED CASH AND WHAT IS THE
OUTLOOK FOR THE AMOUNT OF RESTRICTED CASH NEEDED IN THE FUTURE? AND SHOULD
RESTRICTED CASH BE NETTED AGAINST DEBT TO CALCULATE THE DEBT TO EQUITY RATIO?

The increase in restricted cash throughout 2006 is primarily due to an increase
in the amount of secured financing debt outstanding and therefore an increase in
the amount of assets pledged as collateral for these financings. Daily
collections on these pledged



assets are held as restricted cash. On a monthly basis, the restricted cash is
utilized to pay interest and fees and then either to pay down principal or
remitted back to the Company. To a lesser extent, the increase in restricted
cash is due to an increase in the amount of funds required to be placed in
trusts to cover potential claims to be paid by our third party vehicle service
contract administrators ("TPAs"). Of the $45.6 million in restricted cash at
year end 2006, $30.9 million related to our secured financings and $14.7 million
related to the funds in trust for our TPAs compared to $6.3 million and $7.2
million at year end 2005.

In addition, we are required to maintain a reserve account for each secured
financing. At this time the required reserve amounts for each secured financing
are minimal.

In 2006, the average interest rate earned on restricted cash was approximately
5.0%.

If we increase our debt levels over the next several years, we will likely
continue to increase our utilization of secured financings, which for the
reasons described above will result in an increase in the amount of restricted
cash on our balance sheet. Restricted cash related to secured financing debt has
on average been about 10% to 11% of the amount of secured financing debt
outstanding.

While most of the restricted cash on our balance sheet relating to secured
financings is intended to repay debt, excluding restricted cash from our debt to
equity ratio is consistent with the way the debt to equity ratio is computed in
our loan agreements.


5. WHAT IS THE CURRENT THINKING ON CAPITAL STRUCTURE WITH DEBT TO EQUITY NOW
RUNNING AT 1.8:1 (EXCLUDING RESTRICTED CASH) AS OF THE END OF THE 4TH QUARTER?

5A. WITH THE STOCK PRICE NOW WELL BELOW THE PRICE OF $31.50 WHERE YOU TENDERED
FOR STOCK AT THE END OF THE 3RD QUARTER COMBINED WITH THE IMPRESSIVE AND
ACCELERATING GROWTH IN ORIGINATIONS IN THE 3RD AND 4TH QUARTER AND THE STILL
MODEST (FOR A FINANCE COMPANY) DEBT TO EQUITY RATIO, WHAT IS THE CURRENT
THINKING ON FUTURE STOCK BUYBACKS?

Although we have increased our use of debt, our capital structure is very
conservative by industry standards. However, given our increase in debt, we are
most comfortable taking more time to evaluate our current position before
increasing our leverage further.


6. WITH THE PRICING CHANGES, LICENSE FEE CHANGES AND THE DEPARTURE OF YOUR
PRESIDENT, WHAT IS HAPPENING FROM A QUALITATIVE STANDPOINT AMONG YOUR SALES
FORCE, DEALER PARTNERS AND OPERATIONS PERSONNEL? HAVE THERE BEEN CHANGES TO THE
WAY IN WHICH THE BUSINESS IS BEING CONDUCTED? HOW WOULD YOU DESCRIBE THE CULTURE
AT THE COMPANY AT THIS TIME?



We are very proud of our culture and the people on our team. Our success as a
company, which we believe to be somewhat unique in our industry, is a direct
result of both. We believe we have good communications with all of the parties
you reference in your question, and we use this to continually assess our
strategy and our approach.

Having said this, we believe the best way for you got get insight into our
current "qualitative" position is to talk to automobile dealers, particularly
those that focus on the sub-prime market. Over the long-term this will provide
you with much better insight than anything we could say here.


7.  WITH 45 DAYS NOW COMPLETED OF THE 1ST QUARTER, HOW HAS THE NEW
LICENSE FEE CHANGE IMPLEMENTED ON 1/1/07 IMPACTED DEALER-PARTNER
ATTRITION? IS THIS SOMETHING THAT YOU EXPECT TO BE A GRADUAL IMPROVEMENT OR
SOMETHING MORE IMMEDIATE? ALSO, WOULDN'T THIS BE LESS OF AN IMPEDIMENT TO
SIGNING NEW DEALER-PARTNERS AS WELL?

It is too early to say what impact the change will have. So far, the reaction
from our sales force and dealer-partners has been positive.


8. REGARDING THE CHANGES IN PRICING AND LICENSE FEES, YOU MENTION THAT DUE TO
HIGHER UNIT VOLUMES YOU EXPECT TO HAVE HIGHER ECONOMIC PROFIT THAN WITHOUT THESE
CHANGES. WHAT IS THE BREAKEVEN INCREASE IN UNIT VOLUMES NEEDED TO OFFSET THE
DECLINE IN ADJUSTED RETURN ON CAPITAL? AND DID YOU FACTOR IN THE INCREASED RISK
OF THESE CHANGES WHEN LOOKING AT YOUR COST OF CAPITAL?

Although the pricing changes reduced our expected return on capital, the changes
have also increased the average capital invested per unit. As a result, in order
to achieve the same economic profit as before, a very small increase in unit
volume (2-3%) is required to breakeven.

We agree that the changes in our pricing have resulted in more risk primarily
because the spread between the collection rate and the advance rate has
decreased. The impact of this was quantified and included in our pricing model,
although not as an adjustment to our cost of capital.


9. I BELIEVE THE STOCK HAS PULLED BACK BECAUSE OF ALL THE CONCERN AND MEDIA
COVERAGE OF SUB-PRIME MORTGAGES, INCREASED DEFAULTS, ETC. SOME ARE LINKING THE
ISSUES W/ CAC AND AUTO LOANS, WHICH, SEEMS FAIRLY ABSURD (I DOUBT MANY OF YOUR
CUSTOMERS HAVE MORTGAGES). BUT THE ONE REAL CONCERN IS WHAT THE HYSTERIA COULD
DO TO THE FUNDING MARKET - I.E. YOUR ACCESS TO CAPITAL. IS THAT SOMETHING THAT
YOU ARE WEARY ABOUT OR DO YOU THINK CAC HAS ESTABLISHED ENOUGH CREDIBILITY W/
ITS LENDERS THAT IT SHOULDN'T BECOME AN ISSUE?



We believe that we have good relationships with our lenders, that they
understand our business and that they are comfortable with their position as a
lender to Credit Acceptance. In addition, we think that our lenders believe that
the factors that have contributed to recent negative developments in the
sub-prime mortgage market have not existed to any meaningful extent in the
sub-prime auto finance industry in recent years. As a result, we are comfortable
with our current access to capital. Since conditions in the debt markets can
change rapidly, we intend to monitor the situation closely and manage our
lending relationships carefully.
