By those 60k miles they need about 3-4k worth of repairs and or maintenance things done IE brakes , suspensions, fluids etc
It was more economical to just get new ones and trade them in due to the high resale value especially on the wranglers
That being said if you’re in love with the truck get it and just fix things as they come. Look into the oil filter starvation issues etc if you’re thinking long term. I just learned to push the pedal down while cranking to prevent it from firing off when sitting for prolonged amounts of time . Our last JK had only 63k miles and was maintenance regularly but already had top end noise so we got rid of it .
