Here's the thing with mileage on 20+ year old vehicles. It really doesn't matter if it's in good shape.
I currently have a 1993 Chevy C1500 that was owned and bought new by my great aunt. It has 230,000 miles on it on the original 4l60e. It's on the original radiator, ball joints, control arms, tie rods, steering box, etc. I was the 6th or so owner of a 2003 TJ with 115,000 miles. It was the most unreliable vehicle I've ever had. Fun? Yes. Reliable? Fuuuuck no. The attention to detail and the want of return on investment the original owner of a vehicle has after they spent what's likely equal to $60,000ish in today's dollars on an LJR is nothing to disregard. They're much less likely to let the "little things" add up until they turn into big things.
If it's looks good and drives good, it's probably in good condition even after 193,000 miles. 1 owner vehicles are generally much better off. Think about it, if you paid a LOT of money for something new, you'd probably want to take care of it very well as long as you have it. Many of the Jeeps out there are in bad shape because the 3rd or 4th owner only paid maybe 5k for it and could care less if it lasts another 50,000 miles.
