Some of them 70s and 80s cars are worth money to derby drivers. Depending on how clean they are. For example, if there was a mid 70s chevy wagon out there that is clean rust wise. It could possible fetch as much as 1000 bucks or more realistically 700-800. No idea what scrap prices are in your area, so maybe this isn't as good as sounds too me. But still worth possibly looking into. If this interests you, let me know. I'd be willing to help as much as I can track down buyers.
