Geo was a brand of small cars and SUVs marketed by General Motors and sold through Chevrolet dealerships throughout North America beginning in 1989 in the United States and 1992 in Canada. Their original slogan was "Get to know Geo." Originally formed by GM to compete with the growing small import market of the late 1980s, the line continued through the 1997 model year, after which the remaining models joined the Chevrolet lineup. The 1990s saw fading consumer interest in the economy compact market, and the last vehicle of the former Geo line, the Tracker, was discontinued in 2004. In Canada, another import marque, Asüna, was introduced in 1993 to provide Pontiac Buick GMC dealers access to a similar range of import vehicles. Geo models were manufactured by GM in joint ventures with Japanese import manufacturers. The Prizm was produced at the GM/Toyota joint venture NUMMI assembly plant in Fremont, California, and the Metro and Tracker were produced at the GM/Suzuki joint venture CAMI assembly plant in Ingersoll, Ontario. The exceptions, the Spectrum and Storm, were entirely manufactured by Isuzu in Japan. Geo Metro convertibles were built by Suzuki in Japan.
The Spectrum was a short lived compact based on the Isuzu I Mark and one size up from the Metro. The Spectrum was previously sold as a Chevrolet model, and was added to the Geo lineup to offer potential buyers an option other than the Geo Metro. The Geo Spectrum was only sold in 1989 until being replaced by the Isuzu produced Geo Storm hatchback.
