Great, great place to get a good sense and feel of what kind of pre-owned car to buy. Its convenient when you want to take a look at a few cars within the same class and/or price range but don't want to drive across town or where ever to try out the others you had in mind. Service was great and hassle free. My sales agent at the time was very professional and I never had any problems in contacting him when I had a few questions for him, but prices are fixed and non-negotiable.
Minus one star for that ridonkculous "Carmax" sticker you have to place on the back of your car upon purchase.
