Unstuck said it very well.
The 2011 Grand Cherokee should not be viewed as a serious off-road vehicle, that wasn't what it was designed for. I would not view it as an expedition type vehicle either. This new Cherocar is truly a car. It's competition is the Ford Edge, Nissan Murano, and other crossovers.
I've disliked the Grand Cherokees since the first unibody model rolled out. They always seemed to be trying to please two different markets at once. The off-road crowd complained that they weren't more off-road friendly and the "soccer mom" crowd complained that they weren't more highway friendly.
When you are faced with a choice between an off-road friendly Jeep or a highway friendly Jeep, you can now easily choose a Wrangler or a Grand Cherokee. Each vehicle now fits their market much better than years past. This is exactly why I bought a Grand last night. It fits my needs perfectly with options to spare.
If you were given a choice between a Subaru Outback wagon (no turbo) or a 2011 Grand Cherokee, which would you rather drive? I was left drooling after driving the Grand.
My grand will never see Hell's Revenge. It might be cabable of it, but it wouldn't be much fun. That is why I have two Jeeps.
