To be taken with a grain of salt:
I've read tons of posts of SAs or other Tesla reps all saying the same thing: CA deliveries to commence in middle/late December. Yet everyone who reads this forum know this to be untrue. Deliveries HAVE started in California and the Pacific Time Zone. So far, only SR+.
However, my local showroom in Corte Madera seems to have bucked the trend. The last three times I've been in there, asking for updates, they said "end of November, early December" for my order (LR/AWD ordered 10/18). Three separate SAs have all said the same thing when looking up my order.
While I'd love delivery before Thanksgiving, I wouldn't bet a dime on it at this point. But it's interesting they have been saying the same thing all along, and so far they seem to be more accurate than the standard "company line".
