I dunno, I'm partial to the X5 4.6i. While it may be slightly slower than the Benz, I've read that it handles much better, and the styling is more appealing to me, not as minivan-like as the M-class. The Infiniti FX45 might also be worth a look. It also does 0-60 in the low-6 second range and probably handles even better than the Mercedes (same basic platform as the 350Z), all for substantially less money.
