305,000 miles
My 97 has 305000 miles and still going strong.
Original: engine, transmission, front differential and transfer case, and everything else including exhaust. Rear diff went out around 2006-don't know why but has been fine ever since.
The Original alternator died just 18 months ago, with nineteen years and 280,000 miles on it. The starter is still original.
Work done: new rack and pinion about ten years ago
New radiator about ten years ago-but my fault: used regular water instead of distilled, so the plastic tanks got brittle. Fine ever since.
Now I've been fixing small stuff: electric antenna, re-painting the center caps, replaceing the driver's seat left front bolt. Also going to replace the valve cover gaskets, as they are very slightly leaking.
Runs great. Tow with it all the time.
I'll keep this forever unless some knucklehead crashes into me and truly totals it...
