I paid $1500 for my 1977 F100 LONG BED. Body in good shape, paint too, virtually no rust (inside door jam has slight). Its a 302 auto, new tires and 113k. Interior is fair, has ac, psteer and p brakes. I have replaced a fuel line, a few smaller things, plug wires and installed new dual exhaust system, so go about $2100 invested.....am I still OK on this if I decide to resell ?
