I'm thinking about buying a 1994 Mustang Gt convertible 5 spd. It has 130k, no leaks, all stock except k&n air filter, runs good, interior is fair. Only bad is paint is chipping on the rear bumper on the right and there is a small tear in the top by the passenger window. The guy wants 5000 but I think I can talk him down at least 500. Should I buy this thing?
