Accordingly it is possible to comply with additional requests, even those which are not contained in the list of special accessories. Mercedes top of the range model, the 1963 newcomer featured an overhead camshaft fuel injected 6.3-litre V8 self levelling air suspension with iable ride control two three-phase current generators limited slip differential twin-circuit hydraulic brake system twin brake calipers to front four-speed automatic transmission all round disc brakes adjustable steering wheel for rake power assisted steering push-button hydraulic opening and closing of front and rear door windows and central rear side windows, central locking, outside-air thermometer, and separate heating / ventilation systems for front and rear compartments.
