I ordered my M3 Performance on October 16th.
One thing I noticed is that when I visit my order page on my iPhone I see almost everything EXCEPT the delivery time frame. I did notice when I check on an actual computer I have an estimated delivery date of Nov 20th - Dec 18th.
What I don't know is if that date just appeared or it has been there for a while because I generally check from my cell phone. This is very odd and could be why you don't see a estimated delivery time. Mine has had the estimated delivery time for almost a week now that I have noticed it.
Seeing as how you ordered yours just a few days after I did you should see something. Lastly, have you completed all the required tasks? Trade in, Financing, etc??
