A.  Don't assume that the sticker price is the purchase price.

To get the lowest price, go in with a starting price that's based not on the sticker price but on how much the dealer paid for the vehicle. A reasonable price to start negotiations is either 4 to 8 percent over what the dealer paid or the CR Wholesale Price, depending on the demand for the model.

B.  Do your homework.

Thoroughly research your choices. Read a variety of reviews. Check the reliability, safety, fuel economy, and pricing of any models you're considering. And don't wait until the day you plan to buy to test drive the vehicles. If you have a trade-in, know its approximate worth. That will depend on the vehicle's age, condition, mileage, and equipment, as well as where you trade it in.
