Rolls-Royce touring limousines were built to a Robert Jankel design in cooperation with coach builder Mulliner Park Ward, London.
The first Silver Spur Limousine was produced in 1982. 16 cars had the 910 mm (36 in) extended wheelbase, and 84 cars with 1,100 mm (42 in) extended wheelbase were produced in 1984 and later. One car had a 360 mm (14 in) wheelbase extension. These cars were extended at the B-pillar, between the front and rear doors.
From 1991 on, 99 units of the Touring Limousine with 610 mm (24 in) wheelbase extension were produced. The car was lengthened at the C-pillar with an opera window added. Like these earlier models, most of the cars had fold-down occasional seats in the rear passenger area.
The Park Ward Limousine was the last one to be officially extended (610 mm or 24 in, again at the C-pillar) with 70 vehicles produced from 1996 to 1999.
