	The Princess model was updated over the years through Mark I (A120), Mark II (A135) and Mark III versions, the largest variation being the introduction of the long-wheelbase version in 1952 with a longer body and seven seats: apart from that the bodywork and running gear hardly changed, nor did the 4-litre straight-6 engine. The radiator was fairly upright in old-fashioned style and the car had separate front wings, but these cars were always more modern in style than the equivalent-sized Bentley or Rolls-Royce and, for the saloon, the price was little more than two-thirds of the Rolls-Royce.
