I'm sure this comes across as a smart-a** answer, but really, a car is "worth" exactly someone will pay for it. It may not be worth much to me, but to someone who really wants it, and makes 10 times my salary would pay MUCH more for it. I sold an old rifle to a guy who made me an offer I couldn't refuse - just because it was exactly like his deceased Father's old rifle. No way any one else would've given me half as much as what he paid for it. (No, I wasn't taking advantage of the guy - I learned why he wanted it so much after he'd bought it from me). I'd look at the ended auctions on ebay to find one similar in shape to yours and maybe in the same general area to see what it (they) went for. That might give you a better idea - although, I've seen one item go for umpteen hundred dollars and another just like it bring 1/2 that the next week.
