There is nothing common to this specific car. If you dont know what to look for in a 51 year old car I highly recommend you have it checked by a trusted mechanic before buying it. You need to check the condition of the frame, the front and rear suspension, the exhaust system, the condition of the engine and transmission just to name a few general areas. If you are paying for a matching numbers car you have to know how to check all the codes on the engine, transmission, and rear differential.
