Colt Car Company, also known as Mitsubishi Motors UK, was a privately owned business established in 1974 as part of Mitsubishi Motors' global expansion programme for the purpose of importing and distributing cars and light commercial vehicles in the United Kingdom. For the first decade of its existence, British market Mitsubishis were sold under the "Colt" marque until the rebranding to Mitsubishi, which then brought the marque in line with the rest of the world.
Until 2008, it was a 51/49 joint venture between Colt Automotive Ltd and Mitsubishi Motors Corporation. Three subsidiary companies existed: Spitalgate Dealer Services, which specialises in dealer wholesale stocking, Shogun Finance, the retail finance company and Shogun Retail, the retail operations company.
