OK i had it checked it out by my mechanic and he said its fine everything is perfect and the only thing that neeeded to be fixed was the front brakes. the guy said he would pay for it. so... I managed to get him down to 12,000 he got a new paint job, pratically new engine, very cleam interior, and hes paying for the brakes to be fixed. so... im buying it on fri next week. One question tho, youve been spiking 16 17 psi how much is it regularly and how do you change it? chip? thanks
