Don't ever feel that you have to stay with only one sales person at a dealership. If you don't like the salesperson get rid of him like yesterdays garbage. Get a new one right away. You don't have to explain your self either. They are there to screw you out of as much money as possible, educate yourself and protect your self. Never let a single jerk off sales person waste your time. Dont ever let a agressive sales person dictate terms to you, tell them you will do what you feel is best for you and get rid of him. Never talk monthly payments, simply say you are looking for the best price the dealership will offer, you are ready to buy now, and do not intend to waste time making this purchase. So lets have your best price, then look at your watch. If they stall, simply say I am going to buy at a different dealership if I have to, perhaps you can reach me on my cell before I sign a purchase contract. Walk briskly to the door don't pause go right to your car. You need to make it clear that you are in charge not the dealership.
Family and friends beg me to go to the dealer when they are ready to make a purchase. I have had lots of experience doing this. Remember the dealer needs you, you don't need him. Also never act timid, look them right in the eye when you dictate terms to them. Never show anger, weakness, excitement, or raise your voice. If they promise you something, demand it is put in writing. If the dealer wants to put their dealer advertising on your car charge them $100 a month, no dealer puts his name on my suv for free!!!!!!!!!!!!!!
