For enthusiasts and owners of all Siddeley motor vehicles across the World

Latest News: 07/02/2017 - Sapphire Anniversary for Sapphires

Welcome to the Armstrong Siddeley Owners Club

Car Of The Month


Star Sapphire

The Star Sapphire was the last model produced by Armstrong Siddeley Motors and roughly 900 left the factory between 1959 and 1960. The "Star" was a development of the immensely popular Sapphire and in fact the prototype was a modified Sapphire. This prototype was driven up and down the newly opened M1 motorway for many weeks to ensure that the modifications had produced a car capable of handling the latest high speed driving (there was no speed limit on motorways in those days). Indeed with its 4-litre engine, power steering, automatic gearbox and disc brakes the designers had truly produced a "Star" that was an excellent motorway cruiser and also, due to its torque at low revs, a docile and yet powerful town car.

These facts have ensured that there is a higher than average percentage of cars still surviving today as the car is well capable of coping with modern traffic conditions. This particular model is currently on its third owner in its 58-year life having had a recent sympathetic restoration. It can be seen regularly at club and other events in the South of England.
