Geo was an American automotive brand that was introduced in 1989. Geo was created by General Motors as a brand for a range of compact cars that were developed in collaboration with three Japanese automakers. A total of five Geo models were built, all of which were jointly developed. Toyota helped create the Prizm, Suzuki helped create the Metro and Tracker, and Isuzu helped create the Spectrum and Storm. General Motors decided to discontinue the Geo brand in 1997, with the models that were in production being branded as Chevrolets.
