If you do buy the car you will enjoy it. The best thing about the early A-bodies, is the people who own them. I owned muscle cars in the late '70s when they could be bought cheap. I paid $2000 for my rust free, 4-speed, ram air, cameo white '69 GTO Judge. (that Judge was a pooch by the way) The people that owned these cars were diverse, and the fun we had in them was usually illegal, and certainly dangerous. I knew people who could speed shift a big block Chevelle, and roll a joint while doing it. The collector, the investment, the market, THE HOBBY, and everything else that crept into this scene have ruined it as far as I am concerned. These cars used to be about fun...sometimes inappropriate fun.
I like my '71 Demon, and it is pretty high on the cool-meter, but I prefer to hang with the early A-body crowd because they love their cars, and have fun with them, sans the constant $$$ harangue. Parts are still pretty cheap, and I haven't heard of anyone hanging bogus a VIN on a 273 car even if they made less of them than AAR 'cudas. Granted my idea of "fun" has changed somewhat over the years, but I still get a kick out of flippin' the bird to the establishment and burning some gas without worrying about stated value insurance.
Sorry gentlemen...end of sermon.
