Going by memory here. The '89 models came in Base, Pioneer and Laredo. Plus
whatever Wagoneer models they had. Basically it comes down to more features
standard and more options available. My '89 Laredo came with things like Infinity
radio/cassette, lighted visor mirror, tow package and skidplate package. Aluminum
wheels instead of steel, power windows and locks, rear cargo cover, roof rack and
cargo area skid strips. It had a nice cloth interior with vinyl inserts and vinyl and
carpet like material on the door panels. Also the seats were a higher back bucket
instead of the regular seats.
When I bought my '01 I gave my '89 Jeep book/brochure to the guy who bought
1st one- 1989 Cherokee Laredo. 12 great years
2nd one- 2001 Cherokee Limited. Got it before they were gone.
