ignorance my friends... there is a reason why we in the jeep world call land rovers road posers. I wouldn't trade a ZJ/WJ (aka Grand Cherokee) even if you paid me. The grand is much better off road. The options in aftermarkets also allow for it to become a very hardcore vehicle.

The grand cherokee uses the dodge magnum V-8 up to 98 or the AMC designed 4.0 I6. both are linked to a very solid drivetrain, 200,000 miles is not uncommon before rebuilds. The dymler V-8 is now in the GC since 99 and has proven to be just as solid.
