Aston Martin Lagonda Limited is a British manufacturer of luxury sports cars and grand tourers. It was founded in 1913 by Lionel Martin and Robert Bamford. The firm became associated with luxury grand touring cars in the 1950s and 1960s, and with the fictional character James Bond following his use of a DB5 model in the 1964 film Goldfinger. The company has had a chequered financial history, including bankruptcy in the 1970s, but has also enjoyed long periods of success and stability, including under the ownership of David Brown, from 1947 to 1972 and of the Ford Motor Company from 1994 to 2007. In March 2007, a consortium of investors, led by David Richards, purchased 92% of Aston Martin for £479 million, with Ford retaining a £40 million stake. David Richards became chairman of Aston Martin. In December 2012, the Italian private equity fund Investindustrial signed a deal to buy 37.5% of Aston Martin, investing £150 million as a capital increase.
