Vanden Plas Princess 3 Litre mk2
(1961 to 1964)
When BMC facelifted their Austin A99/Wolseley 6/99 models in the autumn of 1961 (at which time they became Austin A110/Wolseley 6/110 respectively), they handed on the same mechanical improvements to the Vanden Plas derivative.
Visually, therefore, the Vanden Plas was virtually unchanged from the original Mk1, but because it had significantly more power than before it had become a genuine 100mph car. Road-testers suggested that it offered 'luxury at a very competitive price', which was exactly the right sort of image which BMC had hoped to develop for the car.
Like the Austins and Wolseleys, the Mk II version of the Princess 3-Litre had 120bhp from its retuned 2.9-litre engine, a longer wheelbase and suspension changes to add to the stability, and it was made even better from mid-1962 when power-assisted steering became optional.
The way to pick the Mk II from its ancestor, incidentally, was to observe that the rear bumper overriders had been moved outboard to be in line with the tail-fins.
