The Austin A135 Princess Long Wheelbase Saloon (DS6) and Limousine (DM4) were introduced in 1952.<ref name=austinsheerlineprincess/> The [[Hydramatic|GM Hydramatic]] 4-speed automatic transmission and [[Hydrosteer]] power steering from Princess IV were fitted from 1956 as options.<ref name=Robson>Graham Robson, The Cars of BMC, page 131</ref> The marque name was changed from Austin to Princess in August 1957,<ref name=Robson/> and then to Vanden Plas<ref name=Robson/> from July 1960.<ref>{{cite news | title=Princess Models | newspaper=The Times | date=12 July 1960 | page=7, col F | issue=54821}}</ref> The long wheelbase models continued to be built by hand in limited numbers as the '''Vanden Plas Princess 4-litre Limousine''', until 1968. All now being parts of British Leyland, the Jaguar Mark X-based [[Daimler DS420]] was initially produced at the Vanden Plas works in Kingsbury, North London then replaced the Vanden Plas Princess within the new, slightly rationalised range. This had been foreseen in 1966 when [[British Motor Holdings]] (BMH) had brought [[British Motor Corporation|BMC]] and Jaguar together, and stopped development at Vanden Plas of the potential successor car. The limousine was luxuriously appointed with much polished wood, optional [[mohair]] rugs and radio with controls in the armrest. Among the long list of available extras were monograms and a flagstaff. The driving compartment was separated from the rear of the car by a division with an optional telephone for the passengers to communicate with the driver. The driving seat was finished in leather and the rear seats were usually trimmed in 'West of England' cloth, the usual arrangement on many luxury cars of the time. Though not as durable as leather, cloth was considered kinder to passengers' clothes. To increase seating capacity two occasional seats could be folded out of the floor.{{Citation needed|date=July 2016}}

The car had [[Independent suspension|independent coil suspension]] at the front with semi elliptic [[leaf spring]]s and [[anti-roll bar]] at the rear. The cam and peg type steering gear had optional power assistance.
