I would say allot it depends on your budget and how much you can afford on replacing, upgrading or restoring the parts and pieces which need it in order to be in fun, safe and reliable condition. I have seen allot of vehicles over the years, some of them appear (body wise) in the worst shape but the running gear is absolutely stunning, rebuilt motors, transmissions, brakes, suspension, etc. Visually they appear like a piece of junk but in reality they run and drive great. On the flip side, I have seen stunning bodies, chrome and interior but the running gear was in horrible shape, smoking motors, tranny slips, brakes are shot, steering is loose, etc. If it were me I would take a great condition running gear and junky body over a clean body and junky running gear, then again, looks aren’t important to me. Nice thing about this approach is the fact you can continue to enjoy the vehicle on the road while replacing body/interior parts as time and money allows. Good Luck and make sure you have fun doing it!
