West coaster here. I also have complained about a lack of communication - albeit the automatic computerized kind. Purchased 1/15 to get supercharger and a $1,000 referral discount (which I thought was ending only for another program to immediately start). Confirmed 1/22. No VIN number through today but promised end of March. My Tesla page has only the reservation number and the "Scheduled for Production" line. I did email my DS two weeks ago and they promptly responded that all was in order. Yesterday as I was leaving work (around 5:00) got an email from the DS that my car would be delivered by the end of the month, that I should log onto financing and arrange that, and he requested info on my trade (which I had decided I would not trade due to their low offer). This was very welcome news. I responded that as soon as I have something telling me the car is less than 30 days out, like a VIN number and that it has entered production, I would get the financing in place. The criticism is all about their computer model as every time I have reached out to the DS or the sales staff I have gotten a timely response.
I note that my order, a MS75 (not a D), was one of the only RWD cars on the order page and I wonder if that has hampered my scheduling.
