Hi - I am looking for some advise on the value of a 1986 Porsche Targa Carrera that I am thinking about buying. Here are the details....175,000 miles, 3.2, kenwood cd, rust free, new tires, new struts, brakes and rotors, starter, fuel lines, heater cables. Original paint is not that great - rock chips, dent is driver's quarter panel. Interior has been stained black....was red - in good condition, just dirty. The AC and CC have been removed. Thanks in advance for your help!
