I've had a Jeep Liberty (as Cherokee's are known in North America) for 9 mths now. Cant comment on the 2.8CRD is mine is 3.7L V6 petrol. I have the Renegade version with both fulltime and parttime 4WD, underbody protection, LS rear diff, rock rails and umpteen watts of roof mounted offroad lighting!
Positives....Its comfortable, looks good and the body feels well put together. Its a comfortable daily drive has performed well in the limited offroading I've done it in and has been great in the snow.
Negatives...Its bloody thirsty (14.5 Mper USG), in 14000kms I've had the front brake discs and onboard computery thing replaced under warranty. There is more transmission noise than I think is reasonable in the 21st century, although the jeep dealer here says its characteristic of the vehicle. (So obviously they go to the same school as Land Rover dealers!
). Oh, and the paint is coming of the plastic clipon wheelarches which apparently isnt covered under the warranty cos, you know I've been driving it on the road so its clearly my fault!
Would I buy another one? No, I have to say I wouldnt, but thats partly cos I would like something bigger but also due to the problems I've experienced with it. The only thing that would tempt me back into one here at least is that they now sell the CRD in Canada. Its about the only diesel SUV out there apart from the monster 6litre 1 ton trucks. With gas prices on the rise, it could be a contender.
Hope these rambles from across the Atlantic are of help!
