FWIW, I went to the local Tesla (store?) and the person said (and I quote) "I can check what's called a Soft Match in my side", which is more representative of what is expected at the manufacturing plant. My EDD is currently Dec 11 - Dec 31 and she indicated that all it says is December and that I should expect it to be "around or before that time". So, basically, I got that they really don't know jack.
Also, the person was extremely clear on 3 points but I have no idea if they were accurate.
1. The VIN is assigned when the car is built. It takes about 2 weeks after that for that car to be delivered to a location.
2. Once the car arrives, they expect you to be available for delivery within 3-7 days. They apparently inspect and prep the car for the first 2-3 days.
3. If you can't accept delivery within that timeline, you are put at the TOP of the list for the next VIN of that config.
Again, I have no idea if these are accurate statements. Plus, it royally sucks that the estimate is technically the entire month of December and so they have pretty much ruined my plans for any holiday getaway unless I'm willing to come back at moments notice.
