I got the same info. April 15th seems to be the magical date.I just off the phone with them too. Got transferred to my actual delivery specialist.
So, they don't know why people that delivered couple days ago got VINs, but they said that the people that configured before April 15th are the priority right now. This "rough date" is probably going to be the cut-off for the first batch at the International centre.
At least I have the extension of my delivery specialist.
My interpretation. They're assigning VINs based on what's available and what they're working on. so those with aero's are getting VINs now.
More importantly, the configuration date will be based on delivery timing so those who configured before April 15 should get their cars first.
Therefore they'll be some who get VINs this week and deliveries in 2 weeks.
They'll be individuals who got VINs but will be waiting another 4 to 5 weeks based on when they configured.
I rather be in the "Former" group
