My older Grand Cherokee 'ZJ' (1994) w/ 318 had 150k mi when I traded it. Still going strong. I should never have traded it, best quality truck/SUV I have ever owned.
My current 2002 'WJ' Grand Cherokee w/ 4.7L has 196,000mi on it. The drivetrain has been flawless until now, it needs some attention. Some other parts of the car should have given me more before failing....
