The Princess is a version of the Austin A99 Westminster produced by BMC from 1959 to 1968, latterly under the Vanden Plas marque.
The model was launched in October 1959 under the name Princess 3-litre.[1] From July 1960, these vehicles bore the name Vanden Plas Princess 3-litre, Vanden Plas having become a badge-engineered brand in its own right instead of being known as a coachbuilder for cars of other manufacturers. The 3-litre was superseded by the Vanden Plas Princess 4-litre R in 1964.
The Princess was a great deal smaller and less than 44 per cent of the price of the older Princess IV Saloon, which was also to continue until 1968.
