Nothing seems terribly amiss with the car from the photos. The stereo, sill plates and cup holder are not original, neither is the red paint on the intake runner and cam covers. The smog equipment is still intact. There isn't any information on the gearbox or other service history, which is important for assessing value. I would want to know when the cam belt was last serviced and the valve clearances checked, or be prepared to do that work right away.
