The Jeep Grand Cherokee was first introduced for the 1993 model year. The Grand Cherokee is a series of mid size SUVs built using unibody construction techniques, which differed from other Jeep models built at the time. The Grand Cherokee was created to be the top of the line Jeep model, combing off-road capability with a refined and well appointed interior. The Grand Cherokee has been built in four generations: ZJ (1993-1998), WJ (1999-2004), WK (2005-2010), and WK2 (2011-2021).
