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

Mikee Likee. It needs some TLC but it looks like it's all here. (down to the original Inland shifter) I'd say a couple thousand or so would be a fair price. My 66 Dart was in a little better shape body wise but about the same shape everywhere else. (Hipo/4 speed etc) I spent $3500 a decade ago. (and your headliner is in 1 piece.)
