I like it...but IMO they're asking too much considering the mechanical condition. Even if you can get it to run without slinging oil you can bet on replacing the brakes all the way around, exhaust, carb rebuild, fuel tank and lines, radiator/block flush (minimum), complete tune-up,etc. All fine and dandy (and fun to work on), but not at that price. I've seen running driving cars for that price. Not trying to discourage you, just saying. I'd watch it for a while and offer him 2k. It won't sell for $4500 in that condition.
