CARMAX REPORTS THIRD QUARTER RESULTS;
                      -------------------------------------

                          Third Quarter EPS of 18 Cents
                          -----------------------------


Richmond, Va., December 17, 2003 - CarMax, Inc. (NYSE: KMX) today reported
results for the fiscal 2004 third quarter and nine months ended November 30,
2003.

         THIRD QUARTER EARNINGS:
         -----------------------

       o Third quarter net earnings increased 29% to $19.1 million, or 18 cents
         per share, compared with $14.7 million, or 14 cents per share, earned
         in the third quarter of fiscal 2003.

         >  The company had expected third quarter earnings in the range of 16
            cents to 18 cents per share, most likely at the mid-point of the
            range.

         >  Excluding $4.5 million of costs associated with the October 1, 2002,
            separation from Circuit City, earnings in the prior year's third
            quarter were $19.2 million, or 18 cents per share.

         NINE MONTH EARNINGS:
         --------------------

       o For the nine month period, net earnings increased 24% to $93.9 million,
         or 89 cents per share, compared with $75.7 million, or 72 cents per
         share, earned in the prior year period.

         >  Excluding $7.6 million of separation costs, earnings in the prior
            year's nine month period were $83.3 million, or 80 cents per share.

         FOURTH QUARTER AND FULL YEAR EXPECTATIONS:
         ------------------------------------------

       o The company estimates that fourth quarter earnings per share will be in
         the range of 19 cents to 22 cents, bringing full year fiscal 2004
         earnings per share expectations to a range of $1.08 to $1.11.

         >  The company expects fourth quarter comparable store used unit sales
            growth to be in the range of 5% to 7%. A fourth quarter expectation
            in this range leads to a full year comparable store used unit sales
            growth expectation of 6% or 7%.

Business Performance Review
- ---------------------------

Sales. "We are pleased that both our comp store used unit sales growth and our
- ------
earnings per share for the quarter came in at the high end of our revised
expectations," said Austin Ligon, president and chief executive officer. "As we
previously reported, in the second half of the quarter we experienced a pickup
in our comp store used car sales rate. We continue to believe there were two
main factors that contributed to the pickup. First, we reduced our margin
targets on selected cars at mid-quarter to improve our price position. Second,
we saw wholesale prices decline at a faster pace in October and November,
consistent with our expectations."

Margins. "Net earnings benefited from our sales growth and from an increase in
- --------
our total gross profit margin," Ligon said. "The gross profit margin increase
primarily reflects better recovery of the costs of our buying operation and
higher-than-expected wholesale margins."

The change to a new appraisal cost recovery (ACR) method has had the effect of
increasing reported used and wholesale margins and decreasing the reported other
sales and revenues margin. Previously, the company had charged an appraisal
processing fee to customers from whom it bought vehicles to cover the expense of
the appraisal, buying, and wholesaling operations. The company now recovers
these expenses by factoring the costs into the purchase offers made.

"The new ACR method also is allowing us to increase our margins in used and
wholesale vehicles with the goal of fully recovering all costs of our buying
operation, including the expense of land on which we hold vehicles waiting for
wholesale," said Ligon. "Absent the effect of the ACR change, our gross profit
dollars per used vehicle would have declined as a result of the price reductions
we took on selected used cars this quarter to improve our price position.

"The wholesale margin also benefited from the flatter-than-normal pricing early
in the quarter, said Ligon. "During the first half of the quarter we received
higher prices at our in-store wholesale auctions than we had expected."

SG&A. "Last year's third quarter SG&A ratio of 10.9% reflected 50 basis points
- -----
of one-time separation costs. This year's SG&A ratio of 10.7% reflects added
costs of being a stand-alone company and the added expenses for our growth
plan," Ligon said. "Growth plan expenses relate to a higher number of newly
opened stores this year compared with last year, as well as the continued
building of management bench strength to support future store growth." The
company estimates that incremental costs related to being a stand-alone company
were approximately $1.5 million more in the third quarter this year than in the
same quarter last year. October 1 was the first anniversary of the company
becoming a stand-alone company and was the anniversary of the major
step-function increase in expenses related to operating independently.

CAF. Third quarter CarMax Auto Finance income was $17.6 million, down 8%
- ----
compared with $19.2 million last year, reflecting the effect of rising funding
costs, which more than offset the benefit of the growth in the loan portfolio.
CAF gain income as a percent of loans sold was 3.8% in the current quarter
versus 5.4% in the corresponding period last year. "With third quarter funding
costs rising faster than consumer rates, we experienced a compression in spreads
generally in line with our projections," said Ligon. "We expect the CAF spread
to be near the mid-point of our normalized 3.5 to 4.5% range in the fourth
quarter." During the third quarter, the company adjusted the upper end of the
cumulative default range assumption used in valuing its retained interests from
2.4% to 2.5%. This adjustment had no material impact on the company's earnings
and related only to the performance of the 2001-1 and 2001-2 pools of
receivables.

Fourth Quarter and Full Year Expectations
- -----------------------------------------

"With the improvement in our used car sales rate, we now believe fourth quarter
comp store used unit growth will be in the range of 5 to 7%, bringing the year's
used unit comp growth to 6 or 7%," Ligon said. "Earnings per share for the
fourth quarter should be in the range of 19 cents to 22 cents, bringing the
expected earnings for the year to a range of $1.08 to $1.11 per share. In
addition, pending sales of new car franchises, if they occur in the fourth
quarter, could add a penny to fourth quarter earnings."
