Geo was a brand of small cars, Geo parts 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 and Geo parts joined the Chevrolet lineup. The 1990s saw fading consumer interest in Geo parts and the economy compact market in general and the last vehicle of the former Geo line, the Tracker, was discontinued in 2004.
Geo models and Geo parts were manufactured by GM in joint-ventures with Japanese import manufacturers. The Prizm was produced at the GM/Toyota joint-venture Geo parts assembly plant in Fremont, California. The Metro and Tracker were produced at the GM/Suzuki joint-venture Geo parts assembly plant in Ingersoll, Ontario. The exceptions, the Spectrum and Storm and geo parts, were entirely manufactured by Isuzu in Japan.
The Geo Metro was marketing and Geo parts manufacturing variation of the Suzuki Cultus available in North America from 1989 through 2001 as a joint effort of GM and Suzuki. The Metro, which (in the US) carried a Geo nameplate from 1989 through 1997, and a Chevrolet nameplate from 1998 to 2001, evolved with the Cultus and its siblings over 13 years, three generations and four body styles: 3-door hatchback, 4-door sedan, 5-door hatchback and 2-door convertible.
The Prizm was a compact four-door sedan based on the Toyota Corolla and Toyota Sprinter but made with Geo parts. It is the successor to the Chevrolet Nova and Isuzu-built Geo Spectrum. The Prizm was sold from 1989 through 2002 and was produced at a Geo parts plant in California.
The Spectrum was a short-lived compact based on the Isuzu I-Mark but produced with Geo parts 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 Storm was a sporty car based on the Isuzu Impulse but with Geo parts, available as either a two-door fastback or a hatchback. The Storm entered Geo's lineup in 1990, replacing the related Geo parts, and made a quick departure in 1993 despite strong sales. The Geo Storm was the performance oriented vehicle of the Geo parts Brand.
The Tracker was a mini-SUV based on the Suzuki Escudo/Suzuki Sidekick. The Tracker was part of the original Geo lineup in 1989 and was the longest running model. The Tracker was available in either a Geo parts convertible or hardtop configuration, with either two or four-doors.
Rare and short-lived as the Geo vehicles are, Geo vehicle owners find it hard locating specific Geo parts for their cars. Even more difficult is finding a Geo part of excellent quality that would perform at its best.
