Wow, thanks again everyone for the kind words!
To reply a few questions:
This post would probably explain what Combox does much better than I would

Tires- The moment I left the dealership I went to get snows installed. I have Pirelli Sottozero 240 non-RFT in the OEM 245 front/275 rear size.
VDC ride- I can't compare to a non-VDC equipped car. Haven't driven one. However, I can tell you in normal mode it's a REALLY smooth ride... almost benz like. Smoother than my previous X5. Sport mode is comparable to a sport pkg E70.
About the XLine- It comes bundled with the executive package in canada, so it was a special order delete.
