My DH worked there for about a month (only quit because he needed more money)...but according to him, they have good cars, and their salespeople make the same profit on EVERY car, so they won't pressure you into anything you don't want for their benefit.
You MAY be able to find a better deal somewhere, but you'd have to work for it..and it is hard to find a dependable one.
You get what you pay for as 'they' say!
