The first rule of buying a car is never admitting to dealer that you intend to buy. If you let the dealer know that you intend to pay, he or she will get to set the terms of the bargain. Instead of admitting that you are ready to buy, do some research first and when you go to the lot, do not say that you are ready to buy without offering a price. Then, give the dealer a price only slightly higher than the wholesale price for the car and make him or her try to bargain with you.
