There more concerned with you stealing from them, then if your actually capable of doing the job. Carmax is successful because morons who don't like negotiating walk in and pay whatever the dealership tells them. If your not intelligent enough to work a deal, then go to Carmax and let them rip you off, how do I know they are ripping people off? They are the highest grossing retail car sales company in the country.....where do you think that gross comes from, idiots who don't like negotiating and will pay what you tell them to......
