Riley RM Roadster

It might look like the definition of an antique car, but under the skin the Riley RM Roadster was an advanced machine. Built to traditional methods with a separate chassis and ash-frame bodywork, the RM was Riley's first post-war car, and although the construction might have been old-fashioned, the engine and suspension certainly weren't. Power came from a revvy 1.5-liter twin cam unit that gave it a surprising turn of speed, while a fluent gearchange and hydraulic brakes meant driving quickly was also safe. At the rear, the car had semi-elliptic leaf springs, while independent torsion bars at the front meant it had good roadholding. The RM was a touring car in the most traditional British style, and in drophead form was rightly considered very desirable. However it was not a great export success and as a result the Riley RM series is much prized today.
