$600 is a fair price for rare machines, particularly the 160, in a rare color with paint/cabinets in excellent condition. Repainting is the most expensive ordeal in restoring machines of this age. Mechanicals of the washer are basically the same through 1989. If the inner tub shows common wear due to the Bakelite agitator, a white tub from an 80's stacked unit can be swapped in as well as some first gen small capacity LAT machines. For improved performance, swap in a Powerfin agitator and 63 OPM gears or keep the original gearing and install a 50Hz pulley and achieve 67.5 OPM's with a 756 RPM spin. Mechanically, the dryer is the same through 1975. Easy restoration for someone who enjoys working with their hands.
