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.
