I have the same issue - they gave me a VIN on the evening of 9.9, saying pickup ready 9.13-9.19... pretty dumb considering no one's gonna do financing on a Saturday/Sunday. Anyway, I have everything accepted and completed in their system as of 9.14, and no option for delivery - they just keep...
Got a VIN last night, history is as follows:
7.21 Ordered white ext/black int, no FSD midwest, projected delivery was sept-oct on order screen
EDD1 10.26-12.7
EDD2 9.17-10.15
EDD3 9.21-10.5
VIN received 9.10
EDD4 9.13-9.19
Ordered a white/black m3p last week - was expecting October delivery at worst, but dates came back as Oct 26-Dec 7. Mildly considering getting a used one now as I don't really want to wait until December.
