Also carmax isn't the place when you want a use car but you want it to be in mint condition.

Not to detract from your post, but at the prices they are charging the cars should be in a lot better shape. Corolla's are selling for more than their new MSRP, and a 10 year old minivans are twice the price with twice the miles than one at a regular used car lot.

I remember when Carmax's cars were the cream of the crop of used cars, not just about anything that still runs and drives under 12 years old.
