I've seen a couple 64 4-door 'Cats with buckets and console, they were pretty cool. I like this car, it looks like it's fairly well kept and the price, while a little high, isn't too far out to lunch considering what you end up with. There would obviously have to be some room for negotiation there, but if the car is actually as clean as it looks, it may not be a bad deal for a nice sleeper.
