Sales of the three-door began in the United States during the second quarter of 1989 under the Isuzu Amigo name. A 2. 3-liter 4ZD1 inline-four engine, producing 102 hp (76 kW) came standard with the RWD while the 4WD was offered with the 2. 6-liter 4ZE1 engine. The transmission was initially manual only. There were very limited options for the early Amigo including air conditioning, seating for two or four, and two trim levels to choose from, S or XS. Some of the model year changes throughout production included: small cosmetic alterations for 1991, the standardization of the 2. 6-liter engine for 1992, and the added availability of a four-speed automatic transmission on the RWD version for 1992 and 1993. No major changes were made for 1993, but for 1994, a high mount rear stop light was added, power steering and mirrors were made standard. The Amigo was dropped by Isuzu in the US market in 1994. A limited number of XS-F editions (with the "F" standing for "Frontera") were produced which had additional options such as power windows and locking, four-wheel anti-lock brakes (ABS) (inactive in low-range 4WD mode, only active on the rear wheels in 4WD high-range). This version of the Amigo had only 49-state emissions (reasons unknown) and there are no official sales numbers, although most dealers agree there were fewer than 75 sold. The only badging that shows this model is a sport blue XS symbol with a sport-font "F" beside it (also sport blue).
