Just got a call from my DS today. Confirmed my delivery appointment for 12/27. He said that was a worst case scenario if it was shipped by rail but it may arrive sooner since they are shipping many via truck. Almost here - appreciate the support everyone. I know many are still waiting - I am sure they will get them moving soon. Mine started production on Thanksgiving and completed less than a week later so some seem to be coming off the line quickly.
DS said it would be on a truck soon and he would have a specific date when it was halfway across the country - apparently very few updates in the system until it is well on its journey.
My Tesla still says "in production" by the way. Got the official e-mail with my delivery appointment date/time though - so looks like the website info is just out of date.
Some details if anyone is interested - just updated the tracking spreadsheet:
MX90D, East Coast, 6 seat everything except towing, 11/5 confirmation date, 11/24 prod, 11/30 prod complete
