Malcolm Bobbit states "The P4 set the seal on the future with a vengeance. Rover defied its critics with the P4's new look and to get some idea of the shock of the new, consider some of its rivals . . . astonishment at the P4's courageous styling." The P3 had almost no boot at all yet that had been considered rather more than adequate. The new car's bonnet-like extension to its rear was ridiculed; the driver sat well forward looking out over a relatively short bonnet and the rear wheels were set well back behind the back seat. All the new car's proportions were different from all the other new cars.
