 It featured a comprehensive ventilation and heating system and a 5-band radio, all of which could be controlled from the rear, electric windows, vacuum-operated screen wash, windshield and front door window defrosting.
 It was powered by a 6.0 L V8 engine producing 200 hp connected to an automatic transmission (similar to that of Chrysler's PowerFlite and influenced by it, but different in design) giving a top speed of 170 km/h , hydraulic drum brakes with a vacuum servo booster, coil and wishbone IFS.
