Ultra-refined and rugged just don't go hand-in-hand beyond a certain point and then something has to give. You can get into trouble trying to do everything well and spreading yourself too thin. Besides, you can only make a high-riding SUV so sporty anyway. Hey, I'm sure it is a great vehicle in many ways and I admire the ballsy move into the SUV arena, though.
Dallas4U, that Mercedes does have the edge on the VX in a few ways, though. And I don't think an SUV should have to be excellent off-road, but it should be fairly capable and do it better than a car and be AWD. That's just my opinion though and it depends what "utility" means to you. Nothing can do it all the best, but to me a true SUV is supposed to do all of it respectably. Yet many (if not most) are underpowered and don't really do any of it all that well.
