I love the Silver Shadow and in its day it had every luxury option possible. Gear change, windows, seat adjustment, fuel filler cap, aerial, air conditioning and heating were all electrically operated. A hydraulic system with pumps operated from the cam shaft was also a considerable advance, as were power-operated disc brakes and self-leveling independent suspension.
The Silver Shadow II was introduced in 1977 and was an improved version of the earlier model with changes in external appearance, particularly wrap-around black bumpers with an air dam underneath; handling was also improved. From late 1977 the side-marker lamps were deleted. From mid 1978 on head lamp wipers were mounted.
The Silver Shadow and Silver Shadow II were destined to become the best-selling Rolls-Royce cars ever produced and they remain to this day a Great British icon.
