Although it is a common misconception that the Jeep Wrangler is a direct descendent of the popular World War II Willys MB, it was actually a replacement for the American Motor Company’s CJ model. The CJ had a strong and loyal fan-base, but the manufacturer wished to boost sluggish sales by offering a sport utility vehicle with a wider appeal and a more comfortable ride. The Wrangler featured a redesigned look and easier handling while maintaining some of the more popular features of the CJ, including a similar leaf spring suspension. Originally produced at a Jeep plant in Ontario, Canada, the manufacture of the Wrangler was moved to the same Toledo, Ohio plant which produced the Willys MB in 1992. This accounts for the erroneous connection often drawn between the Willys and the Wrangler.
