2 week window means your getting closer. You can reach out to the SA but that two week window can get pushed, sometimes multiple times, so hard to say when you will get delivery until you get a VIN.
I really don't know who my SA is. I ordered online on Jan 9th and then scheduled delivery for Princeton, but then changed it to Springfield. I have been to the Springfield location a few times for test drives and have spoken with the SA there and yesterday he told me that the 2 week window means it should be very close to having a VIN assigned but they can't be certain.
