Used car haggling

I tell them they have one shot...if they can't make the decision then I want to talk to the person that can...I'm not playing the back and forth game. You are probably better off not trading in a car...because they can double bang you on that deal. Or if you do trade it in do the Apples for Apples...if they quote you retail on there car..get retail for your car. Know what your trade is worth. Know what their car is worth. Have it printed out so that you have something to go by.
I told the last sales guy I'm not setting here why you go smoke a cig with your boss....when you come out of that room you had better give me your best shot. Then if the shot's not good enough I leave. Call me when you want to make the deal...see ya. My wife always leaves the fun stuff to me..:) I was raised around used car lots...my Dad love to wheal and deal.
