Originally a green car so maybe they were using the other colors (yellow, blue, orange) to seal the exterior from rust - or to paint over it? Rear passenger side door sill, bottom corner of the passenger rear window, the big patch at the top of the body above the passenger rear wheel, and the crusty area of the rear passenger side floor board all suggest this is a basket case. Maybe some really talented body & paint guy with a need for a multi-year project could bring this car back? I am digging that air cleaner though - gotta get me one of them! (lol)
