My dad is looking into getting a Grand Cherokee, either a 1998 5.9 Limited or an early WJ. It would be a 4x4 V8 Auto on either one. It would be driven about 140 miles daily, mostly on highways, but we would take it to local trails every once in a while. A friend of ours has a 1993 Limited, and my dad loves it, but likes the extra features the 5.9 has. Which would be a better buy for him?
