Congrats!!! My wife and I just placed our order (we're in Canada), for a fully configured X6M - Sapphire black, black interior. She'll drive this in the winter, mostly (2006 Z4 M for the summer).
Do you have to do the usual, M break-in period?
Do you have ventilated seats? We were told we could only get the ventilated seats if we first special ordered the "Comfort" seats (which, I would think, would be a step down from the M seats), THEN order the ventilated seats - just over CDN$2000 to do so. We crammed it - not worth it.
I'm going to have to work on the M3... something tells me my wife is going to be able to take me down in a straight line....
