The Isuzu Trooper was a mid-size SUV produced by the Japanese automaker Isuzu between 1981 and 2005. It was exported worldwide as the Isuzu Bighorn, Isuzu Trooper, Isuzu Trooper II , Caribe 442, Acura SLX, Chevrolet Trooper, Subaru Bighorn, Honda Horizon, Opel/Vauxhall Monterey, Holden Jackaroo, and Holden Monterey.
There were three generations of Trooper, 1981–1991, 1992–1997 and 1998–2005, after which Isuzu ceased exporting the model. It began production as a rather basic and somewhat underpowered on- and off-road vehicle, offered only with 4 cylinder motor, 5 speed manual transmission, and part-time four-wheel drive. The first generation evolved to add both amenities and luxuries, including optional air-conditioning, power windows, and a more powerful V6 engine. The second generation was more refined yet, available in two-wheel drive as well as four.
