yeah. I have seen xj's with alot of miles but then again its still a jeep motor the straight 6 not a pos dodge motor. I dunno I'm just going on what I've seen and I've seen my fair share of fords needing trans.
But all cars have their issues, take a look at our lovely toyotas, the 3.0 put them in the books for having issues to, had toyota never made a 3.0 or thought the design out a little more they would have never had gotten any bad wrap.
