The Jeep Cherokee YJ/XJ, produced from 1987 to 1996, stands as a testament to the Jeep legacy of rugged off-road capability and versatile everyday driving. The YJ, known as the "square-body" Cherokee, marked a significant departure from its predecessor, the CJ-7, boasting a unibody construction for enhanced strength and durability. It was available with either a 2.5L four-cylinder engine or a 4.0L straight-six engine, both paired with either a five-speed manual or a three-speed automatic transmission. The YJ was renowned for its solid axles, high ground clearance, and optional four-wheel drive system, making it a popular choice for off-road enthusiasts.

The XJ, introduced in 1984 and carried over until 2001, was a major evolution, adopting a unibody construction for improved handling and ride quality while maintaining its iconic ruggedness. It was offered with a range of engine options, including the 4.0L straight-six engine and, later, a 2.5L four-cylinder engine, as well as a 2.8L diesel engine. The XJ's versatility extended beyond its off-road prowess, becoming a popular family vehicle due to its spacious interior and comfortable ride. Its distinctive design, featuring a rounded hood and a prominent grille, cemented its place as a recognizable and admired icon in automotive history.
