Jeep Wrangler YJ (1987-1995) In 1983, the growing market for compact 4WD vehicles still sought the utilitarian virtues of the Jeep CJ series, but consumers also were seeking more of the “creature comfort features” associated with passenger cars. AMC responded to this demand in 1986 by discontinuing the CJ series and by introducing the 1987 Jeep Wrangler YJ. This was the first and last Jeep introduced with square headlights.
