Riley RM Roadster (RMC). 2 + 2

Riley RMC 2+2 Conversion (KXF332)

2+2-seater 2Ż Litre Roadster

The RMC was normally only sold as a 2 or 3 seater, with either two bucket seats, or a narrow three abreast bench seat. Behind the seats was a narrow space for luggage, before the bulkhead and then the main luggage boot. However, this particular car has been reconfigured into a 2+2 format, and presumably a home-built conversion done many years ago. However, it is possible that this is a period coachbuilt variant, the finish being to a high standard. In order to create space for the extra row of seats, the bulkhead has been moved back, with the bootlid shortened to suit. The cut in the lid has been made where it would normally change profile slightly, and so is in a position that looks normal. The rear bench seat was hidden beneath the tonneau cover and some luggage at the time of seeing the car, but looked like occasional seats, rather than the normal RM rear bench. To cover the car, the hood is visibly longer, with a much smaller rear screen in the last fold of the roof, which is ncessarily shallower than on the normal RMC. The overall effect, it has to be said, is of a car that is much better proportioned than the Riley version of the RMC, and it is a wonder that such a car was never considered for production.
