The Ford Cortina is a mid-sized family car built by Ford of Britain in various guises from 1962 to 1982. The Cortina was Ford's mass-market mid-sized car and sold in enormous numbers, making it common on British roads and was Britain's best-selling car of the 1970s. It was replaced in 1982 by the Ford Sierra. In other markets, particularly Asia and Australia, 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. The Cortina was produced in five generations (Mark I through to Mark V, although officially the last one was called the Cortina 80) from 1962 until 1982. From 1970 onward, it was almost identical to the German-market Ford Taunus (being built on the same platform) which was originally a different car model. This was part of a Ford attempt to unify its European operations. By 1976, when the revised Taunus was launched, the Cortina was identical. In fact, this new Taunus Cortina used the doors and some panels from the 1970 Taunus. All variants of the Cortina sold over one million, with each successive model proving more popular than its predecessor.
