I agree T-model66.. appears to be an extremely well-preserved original car, which is also very *rare*.. YES,, Camaros with bench seats are rare...
a bench seat in any of the pony cars are rare; I didn't even know a bench seat was an option in those cars until long after they were new.. and I've only seen a handful in my lifetime since.
Note: I assisted a good friend with restoration of a '70 AAR Cuda, with bench seat and column shift Auto .. How rare do you reckon that is?
