I bought my Jeep with 124,000 on it and have done a lot of driving in 23,000 miles; now it reads nearly 150k but still purrs along like new. I lifted mine 6" on 33" Xterrains and have jumped it, swamped it, flooded it, and she still runs great if you change the oil.
Off road capability, strength, and reliability.
More comforts inside, like comfortable seats, a/c, but other than that none. Maybe lockers and larger tires stock.
