On the phone with Tesla now. In my account is a confirmed delivery date of 09/22. I called with some questions and happened to ask if I had a VIN. She said no, and said it was "really weird" that I didn't have a VIN, but had a scheduled delivery date. Now I'm super nervous again. Was this mass email that the "Delivery Schedulers" sent just a big mistake? I want my car!!
I'm on hold now while she's looking into it.
UPDATE: She just came back and said that she was out for a week and they _just_ changed SOP so people are matched to VINs at the last minute, as little as a few days before taking delivery. She said as long as I see a scheduled delivery date on my account, it's set in stone and I should for sure have my car by then (barring any last minute issues).
Phew. What a roller coaster.
