With those options, I think you did good at that price. I think at the most 10-12k for it as it is. Yes, it is original, but it does need some work cosmetically. I like the originality because you know what you have to start with. I always have liked those Marty cars. I like that it is a hardtop car, that alone to me makes it worth more to me, but there are many out there that would pay more for a hatch roof. With a repaint and interior work, 20-22k at most. If you are in it to try to make money for a flip, I would leave it alone and clean it up real good and sell it as is, otherwise you are going to have more in it than you will get back out of it. Very nice find, and personally if I bought it, I would drive it just as it is.
