The 1998 GMC Jimmy is a compact sport utility vehicle (SUV) that was manufactured by General Motors and sold under the GMC brand. This generation of the Jimmy, known as the "S-series" or "Sonoma", represented a departure from the earlier versions, adopting a more rounded and modern design that aimed to appeal to a wider market. The Jimmy shared its platform and many components with its Chevrolet counterpart, the S-10 Blazer, differentiating itself with subtle styling cues and trim levels. Built on a sturdy ladder frame chassis, the Jimmy offered a rugged and capable driving experience, combined with a spacious interior for up to five passengers. Power came from a range of V6 engines, including the 4.3-liter Vortec, known for its reliability and fuel efficiency. The Jimmy could be optioned with either rear-wheel drive or four-wheel drive configurations, catering to diverse driving needs.

The 1998 GMC Jimmy was equipped with various standard features, including power steering, brakes, and windows, as well as an AM/FM cassette stereo. Optional features included air conditioning, cruise control, power seats, and an upgraded stereo system. While lacking some of the modern amenities found in later SUVs, the Jimmy stood out for its practicality and affordability, offering a balance of off-road capability and everyday usability. However, as with many vehicles of its era, the Jimmy's safety features were basic, relying primarily on passive safety elements like crumple zones and seatbelts. Despite its simplicity, the 1998 GMC Jimmy gained a reputation for its durability and off-road performance, making it a popular choice for those seeking a reliable and capable SUV at an attractive price point.
