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

If it has 56K on the motor, it probably won't take much to get it running. And you won't have to do much of anything to have a really nice car. Probably has 3.23 gears and a sure grip. There is a reason people who had those cars would not sell them for decades after they stopped driving them. It even has a 4 speed console and the 14 x 5.5 wheels, let alone the Formula S lug nuts. $4,100 would be in his hands as soon as he went down that low for me.
