The Rover P5 series, is a group of large saloon and coupé automobiles that were produced by Rover from 1958 until 1973. Models were marketed under the names Rover 3 Litre, Rover 3.5 Litre and Rover 3½ Litre.
The P5 was a much larger car than the P4 which in some respects it replaced. 69,141 units were built. The final iteration of the P5, the P5B, appeared in September 1967. The final letter in the "P5B" model name came from Buick, the engine's originator.
