The Cortina was Ford's mass-market mid-sized car and sold extremely well, making it very common on British roads. It was also Britain's best-selling car of the 1970s. It was eventually replaced in 1982 by the Ford Sierra. In other markets, particularly Asia and Australasia, it was replaced by the Mazda 626-based Ford Telstar, though Ford New Zealand did import British-made CKD kits of the Ford Sierra estate for local assembly from 1984.
