   1.                                                   It appears the second
sentence in the second paragraph of your response to comment 3
                                                        is useful information
to aid investors in understanding how mix in sales by vehicle age
                                                        affected the average
retail selling price and the consequent impact on your revenue.

2.       We have reviewed your response to comment 5. In your response you
state "wholesale
         sales are a complement of conducting [your] retail sales," and you
therefore do not include
         wholesale units sold within your calculation of total gross profit per
unit. Please advise
         why "wholesale vehicle gross profit" would not similarly be excluded.

         Your response also states your wholesale vehicle purchases are in part
to "provide a
         competitive sourcing advantage for [your] operations." Your response
appears to indicate
         wholesale unit purchases (and sales) are designed to be a driver of
your retail unit
         purchases (and sales), as is evidenced by inclusion of wholesale
vehicle gross profit
         within total gross profit per unit. If true that wholesale vehicle
gross profit is attributed to
         used vehicle sales, please advise why the Company performs a separate
analysis of
         wholesale vehicle gross profit per unit using wholesale vehicle unit
sales.
       You may contact Abe Friedman at 202-551-8298 or Doug Jones at
202-551-3309 with
any questions.
