Generally, I love my jeep. It's my 3rd, having had a 1991 Cherokee and a 1995 Grand Cherokee. I was initially sold only because of the warranty and features (the previous 2 had a lot of problems). Now, I'm really happy with it. It rides well off roads, is amazing in snow and mud, and drives reasonably on the road. It's been reliable, even compared to more "reliable" cars a few of my friends purchased at about the same time. The gas mileage seems to be about the same as my 5.2L V8 Grand Cherokee while being a good bit smaller. Also, the ground clearance is limited compared to my previous jeeps. which are my only complaints. Some complain about window controls, but I've had BMW's-same place :)
Generally, it a reliable machine that handles well when you want an SUV to act live an SUV - in the snow and off road. The best deal in the price range with the best warranty and the only one with luxury features like heated seats and leather
Improve the fuel economy, maybe make is a little bit longer and improve the ground clearance.
