Not mine, but in the family:
1996 Cherokee Sport 4WD with ~180,000 miles.
I am a Honda/Toyota fan and I would put that 4.0L up against anything from Japan if we're talking about reliability and performance.
The simplicity of one cylinder head, camshaft and timing chain make me like it even more.
Makes me wonder why Suzuki is the only Japanese mfr to have in I6?
2001 XJ 81k miles
A good friend of mine made it to just shy of 200k with his '94 XJ. That's saying a lot considering he thinks a 15k dino OCI is ok. The transfer case finally died, probably due to neglect, so he bought a 2003 KJ. When I took a look at it I told him to ARX it and start six month intervals of a good group IV, he just looked at me like I was crazy. Oh well.
