Description Very nicely presented 2 1/2-litre; recent expenditure; one of the nicest we have offered Low-slung, rakish and elegant, the RM series was the last range of cars to be developed independently by Riley before the 1952 merger of Riley's Nuffield Organisation with Austin to form BMC.

Originally made in Coventry, by 1949 production had moved to the MG works at Abingdon.

While the RMA and RME made do with a 1.5-litre engine, the RMB and its successor, the RMF, had the 2.5-litre 'Big-Four' with twin camshafts mounted high at the sides of the cylinder block, hemispherical combustion chambers and twin SU carbs.

In RMF form the engine produced 100bhp giving the car a top speed just a whisker shy of the magic ton.

The RMF also had fully hydraulic drum brakes rather than the hydromechanical system of the earlier cars and featured independent torsion bar front suspension and rack-and-pinion steering which gave excellent ride and handling for the era.

In production for less than two...
