Complete and utter disassembly
I did it on a 75 Duster. I was amazed on what people were looking for parts wise. Didn't do much sheet metal, although one guy did want the roof, but it never came through. Parted it out to nothing and then had the wrecker haul what was left of the body away and got $250 for it. I really enjoyed it, tbh. I liked helping other members with parts.
