Truecar gives you an idea of what a certain model is selling for around your area. This service has helped many people know if they were getting a good deal, okay deal, or no deal at all. It gives you leverage with the dealers.
It is generally the same principle of calling up several dealers, and in each subsequent call, you ask the dealer if he can beat the price of the prior dealer. They hate that, but that’s how you get the best deal. They hate it because it works.
That's true. If they're accurate, anyway. I was hoping someone with personal experience would weigh in.
