I've never bought a car from a dealer and one the primary reasons is that I don't want to deal with a salesman. I'd rather get a used car where there's a significant price discount and there are well-established guides (KBB, Edmunds) that wil tell you basically what you should expect to pay. Buying a used car is much more price transparent than buying new. (The other reason is that I refuse to go into debt for something I use for an hour a day and hate every minute of it).
