It was first introduced in the spring of 1973 in Brazil as the Chevrolet Chevette (2-door Sedan), followed in October 1978 by the 4-door Sedan, and in 1980 by a 3-door Hatchback. In October 1980 arrived a 3-door Wagon, later called Chevrolet Marajó. Also available was a pick-up, called Chevrolet Chevy 500, named GMC 500 or GMC 1600 in other countries. In Colombia and Chile there was a Chevrolet San Remo (4-door Sedan) and in Ecuador a Chevrolet Cargo (pick-up). In Ecuador there has also been the Cóndor (fibre glass 2-door Sedan, 2-door Coupe and pickup) built by Aymesa and the wagon was sold as Gacela. In Uruguay, the Brazilian Chevette Wagon was built as Grumett 250M with a polyester body; later it was renamed Grumett Color. There were also a Grumett Sport 2-door coupe and a Grumett pickup, in both 2-seat and 4-seat versions. Later, GM sold the Chevette (2- and 4-door Sedan), also as diesel.

By 1978 the Kadett City was renamed Opel City, and in October 1977 the Opel Rallye was added, a high-performance version of the Coupé. In November 1977 a limited editon series of the Kadett GT/E was released, called Opel GT/E.
In the autumn of 1974 the car was built in Argentina as Opel K-180 (4-door sedan). Later, the Brazilian Sedans were sold in Argentina as GMC Chevette from 1992 to 1994.
In Japan, in November 1974, the car was introduced as Isuzu Bellett Gemini as a 4-door Sedan and a Coupé, 2 years later renamed Isuzu Gemini.
In March 1975, the 3-door Hatchback first appeared in England as Vauxhall Chevette, in June 1976 accompanied by the 2-door Sedan and 4-door Sedan, and in October 1976 by the 3-door Wagon. In September 1976 the Bedford Chevanne appeared, a Van version of the Wagon. In the early eighties, after the introduction of the front-wheel-drive Kadett D, the Vauxhalls were sold in Germany by Opel as Chevette.
In 1975 the Holden Gemini was introduced in Australia as a 4-door Sedan and a Coupé, in 1978 followed by a 3-door Wagon and Van.
In USA, the car was produced as Chevrolet Chevette as a 3-door Hatchback (different from the Kadett City) from September 1975, followed by a 5-door Hatchback with extended wheelbase by the 1978 model year. These cars ware available in Canada as Pontiac Acadian. By 1981, in USA, the cars were also sold as Pontiac T1000, renamed Pontiac 1000 by 1983.
By 1976 the Isuzu Gemini was sold in the USA as Opel by Isuzu, later known as Buick Opel. By 1981, in USA also, the Isuzu Gemini was sold as Isuzu I-Mark.
In Korea there was the Saehan Gemini (Saehan Bird in the export), later called Saehan Maepsy, as a 4-door Sedan, by 1983 Daewoo Maepsy, later Daewoo Maepsy-Na, and Saehan Max, later Daewoo Max as a Pick-up (different from the South-American version), while in Malaysia the cars were sold as Opel Gemini (4-door Sedan and Coupé).
In all, the car has been known under nearly 40 different names.
The Chevette/Gemini/I-Mark/Kadett/Maepsy is not all GM, and not trying to imitate the Japanese, but a collaboration between US, German, UK, Brazilian, Korean, etc. And, it was different for each market because the engine, transmission, and all components were sourced from the market they were built in.
