BMC's Mini, designed by Alec Issigonis, had revolutionized the small car market in 1959, and the car remained among the UK's best selling cars for more than 20 years after its launch, the last version finally rolling off the production line on 4 October 2000 after a run of 41 years. The Rootes Group launched the similar-sized Hillman Imp four years later, but by the end of the 1960s Ford and Vauxhall had yet to launch a comparable product, and even with foreign imports slowly starting to gain ground on the British market, Italy's Fiat 500 was one of the few comparable alternatives to the virtual monopoly of the Mini and Hillman Imp in this sector of the market.
