GM Daewoo Auto & Technology (GM Daewoo or GMDAT) was first established as National Motor in 1937 in Bupyeong-gu, Incheon, South Korea. After changing its name to Saenara Motor in 1962, Saenara Motor was bought by Shinjin Industrial in 1965, which changed its name to Shinjin Motor after establishing collaborations with Toyota.
After Toyota's withdrawal in 1972, Shinjin Motor started a joint venture with General Motors under the name General Motors Korea, but was renamed again in 1976 to Saehan Motor. After the Daewoo Group gained control in 1982 the name was changed to Daewoo Motor. In the early 1990s the company started to expand heavily throughout the world. Until 1996 all cars were based on models from General Motors. After the Asian financial crisis started in 1997, it took over the troubled 4WD specialist SsangYong in 1998, but ran into financial trouble in 1999.
