I had a 1999 for about 2 years. I didnt mind it - kinda miss it sometimes. The 4.0 is a dead reliable engine much like the ranger 3.0, and it's a piece of cake to work on because its an inline (that last plug hiding against the firewall is a pain though

. With a 5 speed and no cruise I got about 18 city and 23-24 highway pretty consistently. Only reason I got rid of it was the local Chrysler dealership made me hate it because the two times I had to take it in, I didn't have it for ridiculous periods of time. Some things to be aware of are that the headers (yes, factory tube headers - look it up) like to crack their welds, and the 1987-89 Renix injected ones had a bass-ackward wiring and injection system. Also, the Peugeot trannies (late 80's) are ridiculously light duty and won't tolerate serious abuse. Stay clear of 1984-1986 models with a V6 because its a GM 2.8 with a Motorcraft carb and a nightmare of vacuum lines and even then was good for maybe 115 HP in top shape which they never are - my buddy had an '86 and it was noisy and wheezy like an old Corsica. That's about all I can throw out there for ya since its been almost 4 years since I had that Jeep, but I read a LOT about them in JP magazine and such, but I just needed something with a bed eventually. Hope that helps.
