so, just an observation: It seems that two things happen on the first day of your current EDD window: you either get a VIN or your EDD jumps further out.
There are quite a few of us that have current EDD's of 4/18 - 5/16. I have spoken to my SA multiple times, and my account is ready to go. I am *hoping* I get a VIN next Monday, 4/18. If I do not get a VIN, I expect that my EDD will get pushed out...
There are a few exceptions, like lfitzsimon, who got a VIN out of nowhere, so most likely that was a car that was declined/passed on for whatever reason, so the system matched the next in line with similar spec at that location. That same scenario has happened a few times in the last ~6months on this very thread.
The guys that don't have any EDD movement, well, I cannot hazard a guess as there could be many reasons ie: trade/financing/account issues/the wind was blowing south... who knows. If that was me, I would be riding the SA/Tesla # being one helluva squeaky wheel!
