Originally intended as a Morris Minor successor, the One-Point-Five emerged in 1957 instead as the sassier sister to the Wolseley 1500. The shell was the same albeit with differences in trim and the front end, where Riley’s traditional grille was fitted. It was under the bonnet where the real fun lay, for the BMC B-series 1489cc had an extra carburettor fitted, boosting output to 62bhp over the Wolseley’s 43bhp. Coupled with Morris Minor running gear, the One-Point-Five was a nimble and entertaining car to drive. The luxurious interior also befitted the Riley image.
