Founded in 1913, GMSA initially distributed Chevrolet vehicles before beginning to manufacture and distribute vehicles of all of GM's brands in 1926. It was sold off and relabeled the Delta Motor Corporation in 1986 as a result of the passage of the Comprehensive Anti-Apartheid Act in the United States and subsequent divestment of General Motors from apartheid South Africa. Following the transition to democracy in the 1990s, GM acquired a 49 percent stake in the company in 1997, and in 2004 the company once again became a wholly owned subsidiary of General Motors, reverting to its original name.
