Star by name, star by nature. Although it looked rather similar to the Sapphire 346, the Star Sapphire was in an entirely different league as far as driving pleasure was concerned. It received a lusty 4-litre straight-six that could deliver genuine 100mph performance – and finally, the four-speed all-synchromesh gearbox was joined by the option of a Rolls-Royce Hydramatic automatic transmission that made driving this swift saloon genuinely easy. Even today, a well-sorted Star Sapphire will surprise other people on the road.
