 Just traded a 2008 Lexus LS460 sedan for my first SUV.  I love it so far!  Loaded with sport package, nav, comfort access, 20 inch wheels, you name it.  I have owned 2 BMW 5 series a few years back and frankly missed the German engineering... especially when compared to Lexus's poor engineering.  Sorry Lexus fans, but they just are not BMW's.  I actually look forward to getting up in the mornings just to drive my X5... that is how much i love it!  Let alone, the service and BMW assist is included for 4 years/50 K miles... that definitely helps with the ownership costs of a luxury SUV.
