ZJ · 1993–1998
Unibody, one plate-glass window, and a launch everyone remembers differently
The ZJ was Jeep's first Grand Cherokee: a unibody luxury SUV at a time when nearly every rival used body-on-frame construction. Development traces to 1983 under AMC, with François Castaing's team carrying it through the 1987 Chrysler acquisition to a January 1992 Detroit reveal — the one where Chrysler president Bob Lutz, not CEO Lee Iacocca, drove it through a Cobo Hall plate-glass window with Detroit Mayor Coleman Young riding along. See /people/bob-lutz and /people/lee-iacocca for why that misattribution persists.
United States market. European-market ZJs (built by Magna Steyr, Austria) and the 2.5L turbodiesel are noted but not fully scoped here.

Configuration
Trims and transmissions
1,647,188 ZJs were built across the run. Transmission was the AW4/42RE 4-speed automatic, or an Aisin AX15 5-speed manual that was dropped after 1994 — meaning most surviving ZJs, especially post-1994, are automatics. Assembly was split between the new Jefferson North plant in Detroit (US market) and Magna Steyr in Austria (European market).
Identify & buy
Identification and ownership notes
ZJs sit entirely within the standardized 17-character VIN era (see /decode/vin). No dedicated buyer-guide entry exists yet for the ZJ specifically — the current /buyer-guide Grand Cherokee coverage starts with the WJ/WK generations; treat ZJ-specific cooling-system and rust diligence as an open research thread, not yet confirmed to match the later generations' known issues.
