Be an Informed Buyer
Needless to say, all of the tips in this article involve researching the cars you want to buy -- to see how they match up to the competition, to see how well they're selling and to see who's offering the best price. But the importance of knowing a lot about the car you want to buy can't be overstated. Before you walk into a dealer, you should have a pretty good idea of what you're looking for and what specific car is most likely to deliver it.
In particular, it's always useful to learn how much the dealer is actually paying for the car. It's unlikely that you'll be able to buy it for less than the dealer's cost and you don't necessarily want to insult the dealer by insisting that they sell the car to you at a loss. But you'll also want to know if you're paying too much. If the dealer sees that you know when a car is overpriced, you're in a better position to bargain for a better deal.
