I'm a huge Mercedes fan. I have always been. However I wouldn't buy the new X class. I would rather buy a Nissan Navara. It would be the same car for less, maybe less prestigious but then again prestige has never been a factor for me when choosing anything let alone cars. They say they have done some suspension work to make it different, but the Navara wasn't a bad vehicle to begin with and their stands look the same so I don't know how much different it can be.
Mercedes should have copied VW, their Amarok is an amazing design. It's comfortable, fast and luxurious for a bakkie. Mercedes could have taken their time and designed their own from scratch, I'm confident it would have been great. It's not gonna matter in the long run though, they seem to be selling them. That's probably their only concern.
