I've purchased only one car from them... but I also helped my sister buy one there... and also two daughters.

ALL went well... and at least at the CarMax in Fresno, Ca. the support has been excellent.

it's not that they always sell at the cheapest price... but in my experience they are always at least close, and sometime cheapest.

It's also nice to have nearly every model there to compare. I did NOT buy my Jaguar there... BUT... when I had narrowed my selection down to three I went to CarMax and they had all three so I could compare/test drive. - JamesJM
