'65 Cuda Fastback
I've seen '65 Barracudas with in dash a/c. I agree that $5900 is a little high for a car in need of paint, I've seen many sell for much cheaper. There's a half decent Formula S in need of some rust repair, paint, engine repair etc but a real nice complete car for $4000 right here ->

I'd buy that before the car you're describing.
