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

Can you do any of the body and-or engine work to save money?
Your ahead of the game because it looks like it has 99% of the trim parts. (looks like the pass. wheel trim is in the trunk. It even has the Formula S lug nuts).
I'd feel safe @ $2500. but $4k if its a must "keeper" car!
Quality resto. and finding right buyer, final value $18k-$22k.
Good Luck!
