Sorry if insulting but let's say 5-$700. You cleaned out his yard or garage plus put cold cash in his hand.If rebuilding is your passion, you know already what it's worth.Personally I would be tired just getting it home,let alone what my wife would say. There are good deals out there. You will know when not to pass it up.Get a running vehicle it makes you smile everyday. Then decide what restore route to take. My 2 cents.
