Need way way more information and 30+ photos to know what you're working with.
Assuming it is solid, mostly rust free, and runs/drives decent but needs some TLC to make it a road-worthy driver, I'm thinking no more than $15,000-$20,000 or so for asking price.
Some might call me crazy, but I just saw one in worse condition than this one go for $14,000 very quickly after listed.
