The Kadett D was introduced in the middle of August 1979, with deliveries on the home market beginning early in September 1979. In November 1979, the car went on sale in the United Kingdom, some five months before the Vauxhall Astra Mark 1, the British version, was launched in April 1980. The cars were designed as three- or five-door hatchbacks and estates or station wagons. There were also two- and four-door sedans featuring separate boots/trunks, which shared the silhouettes of the hatchbacks: in the United Kingdom, the sedan versions were soon withdrawn, until the 1986 launch of the MKII-based Belmont. For the first time since 1965, there was no coupé-bodied Kadett in the range: the previous Kadett C coupé was indirectly replaced by the three-door 1.3 SR sports model.
