3 of my 4 MJs are over 200k, but none are in active daily driver service so the mileage won't get much higher anytime soon. My 97 hryser minivan (the C fell off) has 208k and still gets used, so there's hope that it'll someday get to 300k.
You should tell the guys at the Comanche Club. You might even have the record.
As far as I know, the comanche has the original block and heads, but rebuilt about 15,000 ago. I had the time to let it sit and the funds, and since with that many miles a 117 hp 4 popper probably was running at less that 100 hp (headwinds up hill on the interstate required full throttle), I sent it to S&S engine in Kent Washington, they give a 7 year warranty, but had them add a Delta Camshaft that's a short step up from stock in lift and duration. Put Clifford header on it, but that has been a major headache with their refusal to admit it hitting the block was their fault.
I bought in with about 240,000 on it while living in the Puget Sound area. It was native to that area. When I got it, it had "green stuff" all over the white paint, the interior was wet, and it had been used as a work truck. It had sat for a while in the back of the carlot but when I started it, no lifter or rod noise, and the clutch gave no weird noises, and all the syncro's in the 4 speed felt good. Underneath, it was a solid truck, with good paint, and no rust at all. Paid 1,100 for it. I scrubbed all the green gunk off it, pulled out all the interior and dried it out and used mildew killer on everything, have rebuilt the brakes, put a new steering gear in it, but everything else, except for the rebuilt engine, is original.
My Cherokee 4x2 we bought new. The only work to it other than normal stuff has been bearings in the differential, new radiator, starter, water pump, and crank sensor. It has the original alternator still, and on startup after an oil change, even if I forget to put oil in the oil filter, there is no rod or lifter clatter before the light goes off. Oh, yea, had to put a new headliner in. The old material came unglued.
Both have been the best autos I have ever owned.
