Don't worry, I configured 4/18 and still no VIN or contact..and I'm in the East Bay. I got the June email, so hoping any day now. I did change the color at one point, so I don't know if that put me to the back of the line..
I couldn't stand it anymore so I called today since I was at 6 weeks since configuring. Really didn't find out anything (of course) but it does sound like you won't be contacted until about 3 weeks before delivery when production of your car starts. At this point we may be getting a delivery date before knowing our VIN in many cases even though it's assigned when production starts. I theorize one factor is they got a massive amount of configurations with that 4/18 group and it's going to take a while to work through them all. Combined with (assumed) delaying of 200k U.S. deliveries all rhyme or reason is out the window.
All this is inference or downright wild-ass-guesses on my part and should be valued at how much you paid for it.
