The document traces the evolution of the Jeep Wrangler from its origins as a military vehicle during WWII to the present day models. It started as the Willys MB and Ford GPW designed to meet the Army's need for a light utility vehicle. After the war, Willys began producing civilian versions as the CJ models, which grew in popularity. Subsequent generations included the YJ and TJ models which featured upgrades like more powerful engines and optional features. More recent versions include the Wrangler Unlimited with four doors and the current JK model.
