it sounds pretty legit for the most part, but again given that this is an older muscle car I would try and press him for some history, at least where he got it from. Base in on the premise that for these cars the history is and important part of it. If he is illusive about that, then I might be worried, but if he gives you a plausible story and all of the paperwork is in order and I really wanted it, I would probably go for it. If it is titled (to him), then the VIN had to go through the system; be sure to closely look at the title and registration. I got thoroughly hosed on a car advertised as a 2000 and after getting home noticed the title say 98... (yes I hosed myself). If the title and registration do not match the owner or the car, then you have cause for concern. Lastly, see if the fender tag is there, if you have time you can determine what that car was build with/as and give you a better sense of what you are getting (e.g. it has a 4spd but the tag says auto); might not stop the sale but it would be best to know pre sale.
