What's a '66 Barracuda Formula S, 4-speed project car worth?

Paid $2,800 for my 66 formula S 4-sp barracuda project with zero rust. so far I have put another $6,500-ish into it and still have to rebuild motor yet. Hope this doesn't scare you away, I have had a blast working on it and it helps keep me off the couch so money well spent so far as I'm concerned.
