If the car looks real clean like its actually been taken care of instead of a dealer detail job it might be a good deal. is it a stick or auto. Also put it on the rack and check for coats of rubber in the rear fender wells. If little or no rubber he was not doing a lot of burnouts and probably not abused. Could be a 100k miles of just highway riding. He may have just been a traveling salesman selling Singer sewing machines or ladies stockings and bras or something.
