My car is still on schedule to hit the dealership today. I have not received notice from my dealership (other than acknowledging my emails telling them it is being delivered today), or from BMW. So just because you haven't heard from them it doesn't mean your car is not on it's way :-)
For those of you that are having issues, I would suggest going to the dealership and asking them to run your VIN number in their system. It provides all the info that you would need.
