Crazy not to buy? 67 coronet

I'd buy it if I had the money! That's a sharp car! 4 door or not thats a cool classic. With a 383 can anyone say "sleeper"?
Offer him 4500 for it and if he doesn't throw you out on on your ear you'll have a great deal. If the interior is as good as you say it is the seat cover is easy to fix compared to the other parts tha may need fixing or finding.
