The Riley 4 / Sixty Eight and Seventy Two are cars produced by BMC from 1959 to 1969, under the Riley marque. They are closely related to the Pinin Farina-designed MG Magnette Mark III and Wolseley 15/60 and the simpler Austin A55 Cambridge Mark II, Morris Oxford V pair, sharing the MG's rear styling and engine (with a milder cam). This Riley is the most expensive car in that series. This model's introduction, using the same engine, did not affect production of the smaller-bodied 1½-litre Riley One-Point-Five sports saloon which continued until 1965.
