Riley RMA. (1945-52)

Launched directly after the War finished, this was the car that was due to be launched by Nuffield in the early 40's, but had been postponed, and honed to perfection during the war. The RMA used the excellent Riley 12/4 engine of 1934, mounted on a development of the pre-war 16/4 chassis and with a body derived from the pre-war Continental model. However, despite all of these old and borrowed components, the model was a sensation on launch and can truly to be said the first all new car to be launched in the 1940s, with so many of those available from competitiors being re-hashed versions of the 1939 range.
When Launched, therefore, it was an instant success with Riley Fans, continuing many of the traditional Riley Features that had brought them such a loyal following.

The car was a full 5 seater, 4 door saloon with a graceful, sweeping body design over the tried and tested mechanics. True, there were a number of Morris / Nuffield components creeping in, but the RM series managed to remain different enough. An old Riley feature of fabric bodies made a come back, with the fabric roof covering, predating the Vinyl that was so popular in the 1970s. At the rear was a capacious (for the time) luggage boot, also housing the spare wheel. Twin fillers for the fuel tanks were a clever idea to allow easier fills - how many people wish for this today?!
The RMA was replaced in 1951 by the marginally facelifted RME, after 10,504 examples had been sold, making it the best selling of all of the RM series cars, accounting for nearly half the total.
