Some of these used car buying tips won't be new to you. Often the trick is just to apply what you already know. On the other hand, when it comes to expensive areas of life like buying a car, one new thing learned can save you hundreds of dollars. Try some of the following.

1. Make a low offer. Okay, you knew this one. A trick you may not have used, though, is to make a low offer, and then leave your phone number with the seller. Time has a way of making sellers desperate, especially after you just helped convince them that they are asking too much.

2. Be careful with car price guides. Use the "blue book" etc, but try not to pay more than wholesale. I can't think of many times when people I know have paid more than "bluebook," so these "average" sales prices are doubtful.
