It must be about 3 or 4 years since we had the Grand Cherokee. It was pretty nippy for such a big car, and wasn’t too thirsty. It was comfortable, and long winter journeys, including up and down the A9 were quite relaxing. It had a few gizmos I wouldn’t be too bothered about, such as auto-dipping headlights and mirrors, and there were a couple of little bugs in the touch screen interface (possibly since fixed with an update). It was missed when it went back to the car hire company!
While we had it, we were approached by a guy who’d had the earlier version, and he raved about them, and told us about the Mercedes engine etc. He was planning to buy the same model as the one we had. Interestingly, we spotted him in a newer model a few weeks ago, so he obviously did go ahead and upgrade.
I’m not sure what the ‘owner experience’ would be like, but I’d definitely look into them (and get a decent test drive) if I was looking to buy that type of vehicle.
