Bought our 4WD Sport new 9 years ago. At 99,000 miles, it has been mechanically perfect - not a single breakdown. Only repairs have been normal maintenance items. Ample power for pulling a 2,000 lb trailer over high passes. It's noisy and rides like, well, a Jeep. But on lousy mining roads, it never gets stuck, and is absolutely unbendable. Not stylish, not particulary comfortable, gas mileage is nothing to brag about; it is the ultimate utility vehicle.
Reliability, ruggedness, towing power.
A little sound insulation would be nice. But since the Cherokee is discontinued, it's a moot point.
