  AM General began marketing the Hummer brand in 1992 when it began manufacturing a civilian model of the vehicle. General Motors purchased the brand name in 1998, thus making the 1997 Hummer Hardtop four-wheel drive sport utility vehicle one of the last models manufactured under the AM General name. After the purchase, GM released three vehicles: the Hummer H1, H2 and H3. The 1997 Hummer has some unique specifications to the vehicle itself not found under its previous AM General brand.
