In 1935, S.S. Cars Ltd, Coventry, was an active but still small manufacturer of sports car-like vehicles. However, the S.S. 90 catapulted the company straight into sports car heaven and the SS 100 cemented its reputation for being able to offer competitive sports cars at a fraction of the price of other top products. Although only a few hundred examples were built, today the SS 100 (and its predecessor) is one of the best-known pre-war vehicles of all time. In this report, the author summarizes the history of the SS Jaguar 100. The review is illustrated with present-day and historical photos as well as four original sales brochures, which are rarely seen.
