The Austin-Healey 3000 is a British sports car built from 1959 to 1967. It is the best known of the "big Healey" models. The car's bodywork was made by Jensen Motors and the vehicles were assembled at BMC's Abingdon works, alongside the corporation's MG models. During its production life its nature was changed from an enthusiast's lusty open sports car, albeit with a child-transporting 2+2 option, to a tame sports convertible. In 1963, 91.5 per cent of all Austin-Healey 3000 cars were exported; mostly to North America. The 3-litre 3000 was a highly successful car, which won its class in many European rallies in its heyday and is still raced in classic car competitions by enthusiasts today. British Leyland ended manufacture in 1967, intending its place to be filled by a car with essentially the same engine in a more recently designed monocoque MGB body named MGC. The 3000 sports convertible Mark III was announced in February 1964 its power increased from 136 bhp to 150 bhp by a new higher lift camshaft. SU HD8 carburettors replaced HS6 units increasing the choke size from 1.75 to 2 inches. Power-assisted braking became standard instead of optional. The new car's fascia displayed its speedometer and tachometer directly in front of the driver. Upholstery was now in Ambla vinyl The Mark III BJ8 remained in production until the end of 1967 when manufacture of Austin-Healeys ceased. Only one further car was built in March 1968.[citation needed] In May 1964 the Phase II version of the Mark III was released, which gained ground clearance through a modified rear chassis. In March 1965 the car received separate indicator lights.
