If that car has ZERO rust, I think it's a fair price, but 2500-3000 is more like it.
point out any flaws, and look for rust. Expext to do repairs on the basic things like LIM gaskets, cv joint's, brakes, a/c system, heater, hoses, windshiled, and probably the transmission, if that has not been taken care of, more likely it is going to need help no matter what, even with regualr service.
From the photos, it looks nice, I like the exterior color. Check all the body panels for matching vin numbers.
