I had a 2000 Grand Cherokee and I wish I had not traded it for my F150 to this day.
It was a good looking ride with every option. It had plenty of room in the back with the seats down. I used to sleep in it when camping and Im almost 6'. My WJ had the 4.7 V8 in it and after I installed a CAI I was getting 21mpg on the highway which was a little better than the 19mpg my friend was getting in his 4.0 WJ.
It did real well of road and in the winter. Mine did not have a tow package though but I installed a round hidden hitch receiver on it and it pulled the largest enclosed Uhaal trailer filled to the max from Charlotte, NC to Columbus with no problems allthough I was only gettin like 9mpg in the moutains.
The only problems I had with mine after owning it for about 3 years was the transfer case it had some issues but I traded it in before I fixed it. I beat the shit out of that Jeep on the street off the street and even at the track and it never left me stranded.
Oh and if you end up with a WJ with no tow package let me know. I took the round hidden hitch receiver and wiring harness off and still have it.
