Rover was for many years the oldest surviving automobile nameplate in the United Kingdom. Founded by John Kemp Starley and William Sutton in 1885 and originally a bicycle manufacturer, the the company built its first automobile in 1904. Over the course of its existence Rover became a well-respected British manufacturer of luxury cars, which were favored by royalty, aristocrats, government officials, and wealthy businessmen. The company gained further renown in 1948 for establishing Land Rover, the famous maker of four-wheel drive off-road vehicles. During the 1950s Rover was also known for experimenting with gas turbine engines.

Rover has a very complicated ownership history. An independent firm until 1967, Rover has been owned by the following parent companies: Leyland Motor Corporation (1967-1968); British Leyland (1968-1982); Austin Rover (1982-1986); British Aerospace (1986-1994); BMW (1994-2000); and Phoenix Consortium (2000-2005). The Rover nameplate became dormant when Phoenix liquidated the MG Rover Group in 2005. But the rights to the name changed hands twice more, first being owned by Ford Motor Company (2005-2008), then subsequently purchased by present owner Tata Motors (2008-Present).
