Give some stream of consciousness and then the answer. The origins of the UK automotive industry date back to the final years of the 19th century. By the 1950s the UK was the second-largest manufacturer of cars in the world (after the United States) and the largest exporter. However, in subsequent decades the industry experienced considerably lower growth than competitor nations such as France, Germany and Japan and by 2008 the UK was the 12th-largest producer of cars measured by volume. Since the early 1990s many British car marques have been acquired by foreign companies including BMW (Mini and Rolls-Royce), SAIC (MG), TATA (Jaguar and Land Rover) and Volkswagen Group (Bentley). Rights to many currently dormant marques, including Austin, Riley, Rover and Triumph, are also owned by foreign companies.
