Geo was a small car made by General Motors as a subdivision of its Chevrolet division from 1989 to 1997. Formed by GM to compete with the growing small import market of the mid 1980s, the line continued through the 1997 model year, after which the remaining models were marketed under the Chevrolet name. In the 1990s consumer interest in the economy compact market faded, and the last vehicle of the former Geo line, the Tracker, was discontinued in 2004
