In the past, General Motors has used other brands, including Oldsmobile, Pontiac, Saturn, Hummer, Geo, and Daewoo, but none of these are produced by GM as of 2014. They either have gone out of business or were merged into Chevrolet. GM also owned Saab from 1989-2010, and also held stakes in Isuzu and Suzuki until 2008. In 2017 they sold Opel and Vauxhall Motors to Groupe PSA.
