I drive vehicles fast and hard. My '92 Cherokee is no exception. Since buying it used 11 years ago with 62,000 miles, I've replaced the A/C compressor, oil pan (drain plug was cross-threaded and retapped, found this out at first oil change), and clutch twice, and the HVAC blower motor, and starter. Everything else routine maintenance. I've driven places Humvee owners would fear to tread (the real H1s). This vehicle is outstanding performance wise. 0-60 in 9 seconds and that's how I drive it. I'd buy another one, but I don't think I'll ever have to, it just won't quit!
Purchased my Jeep new. Change the oil every 3 thousand miles using Mobil 1. At 13 thousand miles under warranty head gasket replaced, known issue for some serial numbers. At 161 thousand still has original transmission, ball joints, tie rods, brake parts. Replaced radiator twice until I got smart and got brass tanks and brass core radiator. I have replaced AC expansion valve, starter and steering column. Have broken drivers seat but I am a big ole boy also. Do your maintenance, it pays. I would take this vehicle any where from coast to coast or border to border and not think twice or worry.
Okay, let me say I love my Jeep. But, I've had some overheating problems since day 1. Replaced radiator and components, I still have to get a radiator flush a couple times every summer. I'm told the engine block has internal corrosion causing the blockage. I've got 200,000 miles on my Jeep and can't really complain although buyers should be aware there's going to be upkeep but there's plenty of wrecks to pick from and aftermarket parts. It's loud too and a bit of a gas hog. It's going to be hard to drive something else though, they don't make them like this anymore.
I had mine for eight years and it had 359k miles when it finally lost the #2 cylinder. Even then I drove it around for a couple of weeks on 5 cyls. It loved to tow and to work low and slow. It also cruised nicely at 80 MPH (70+ with the trailer). It got 18 MPG in the city and 20+ on the highway. I enjoyed it as a daily commuter, weekend road trips, four wheeling, and camping with a tent hung over the lift gate. I want another one. Same year, same model, less miles.
