CarMax — hides the truth
As a former employee, I can tell you their standards for the cars they buy and how they fix them up have changed drastically since 2006. It is all about the margain now and not about the cars. You however have to remember you are buying a car that is "used". It is not going to be perfect, but the quality of how everything works is substandard to the way they used to prepare cars for sale. They are very far when it comes to buying your car because the prices come straight from the auction prices from around the USA. Good luck trying to get them to fix anything...they will just ask you to return the vehicle or trade it in.
