what kind of car is it? when you go see it say hey i only got 1500 take it or leave it, if he wants to sell it bad enough then he will give it to you for that price, but remember its eaiser to say no to an offer over then phone then it is when the person sees the cash in hand, just make sure you got the other money tucked away in another pocket just in case, check the body for rust and the frame for rot. make sure every thing looks the way it should, no half ass wiring or shit like that
