Once WWII was over Riley was one of the few manufacturers to launch a brand new model. The Riely RM model had been developed during the war, as it was clear the past models were outdated. With engine sizes ranging from 1.5L to 2.5L, the RM’s were a series of sports saloons constructed from 1945 to 1955. Over the course of production, a range of variants were built: RMA, RMB, RMC, RMD, RME, RMF, RMH (Pathfinder).
