I just bought a 79 Fiat Spider. (North American model) for it's year it is not in bad shape at all. However my plans for this car are to reproduce it as close to mint as possible. My question is where should I start? Engine, Frame, interior, or body. My first thought was to start on frame and engine, then move to cosmetic. But if I lose interest in this project would it be better to have exterior and interior tight for re-sale?
