sorry jeep4 jason. The wj is a joke when compared to the xj. If you want to replace everything under the hood and chassis, keep driving the 'grand'. I had a 95 5spd xj country 260 that rips just as much as my 00 sport w 145k. Biggest issue=broken motor mounts in the 95 from heavy abuse(very heavy)

My 94 has 131,ooo on it with a rebuilt head gasket (there really wasn't a big reason too though, my dad just wanted us to do it)
My mom's 96 has 189,ooo with regular maintenance

My 96 has 133000 miles. It's exempt from pa emissions and there is rust all over the trunk lid. I am a restoration specialist so I'm going to restore this piece to the best of my ability. (I'll be sure to put on a build thread)

136,000 on the dot as of today in my 97. Looking forward to the next 136,000, but hopefully an AX-15 will make its way into the mix somewhere along those miles

haha im a highschooler. and I beat my old 96 to hell. 12k without fluid change and im pretty sure theres a dent in the floor below the skinny pedal. but that was when I was 16 and 17. now Im 18 and more responsible and I have a real nice 99 that I take care real well. but i do totally agree if it was owned by a first time driver in highschool, and it's a jeep, civic, or altima, chances are, they beat the hell outa it.

well at 423,291 have developed a out of balance like vibration feels like a cylinder on a free ride, loss of a little power but the power comes back at 45mph and 2500rpm think fuel inj. may need to get replaced.

My first Xj was a 96, when I got rid of it it had 330K+ and did not burn a drop of oil. Should have kept it. My current 2000 has 100K+ and runs like a top.
