From Jeep press: Jeep Wrangler (YJ): 1987-96. In 1983, the growing market for compact four-wheel-drive vehicles still sought the utilitarian virtues of the Jeep CJ series, but consumers also were seeking more of the “creature comforts” found in passenger cars. The response was discontinuing the CJ series and introducing the 1987 Jeep Wrangler (YJ).
Although the Wrangler shared the familiar open-body profile of the CJ-7, it contained few common parts with its famous predecessor. Mechanically, the Wrangler had more in common with the Cherokee than the CJ-7. The Wrangler YJ had square headlights, which was a first (and last) for this type of Jeep. The YJ model exceeded 630,000 units.
On Aug. 5, 1987, about a year after the introduction of the Wrangler, American Motors Corporation was sold to the Chrysler Corporation and the popular Jeep brand became a part of Chrysler's Jeep/Eagle Division.
