Speaking of how "wanted" the X5 M is in Germany: looking on the german BMW website for used or new X M models, one can find 13 (!) X6 M available at dealers but not a single X5 M. Apparently the X5 M is very appreciated because of its "understatement" looks, something very important in Germany. I live in Bavaria, there are tons of X5s driving around, the X5 M blends in perfectly. The Cayenne was a different story and considering the fact that the Cayenne had a very bad public image (gas guzzler, the most environmental unfriendly car on the planet, etc.) and reputation, the X5 M is just perfect for our society. Nobody really thinks that BMW put 555 horses into a "regular" X5. Perfect undercover rocket.
