I have had no major repairs on my Jeep since buying it in 1980, only standard maintenance, hoses, belts, spark plugs, etc.
My CJ7 had 63000 miles on it when I bought it for farm use. It has had a well serviced, but hard life and is still going strong at nearly 130000 miles. This vehicle seldom sees a paved road and has never had an engine or transmission overhaul, or even a clutch, while I've owned it anyway (although it is about due). It has a hard top and steel doors which I love to remove in the Summer. Can't be beat around the farm. New Jeeps look nice, but my advice is get a CJ7 and rebuild it.
