I also got my finalize e-mail last night, for reservation number 10,074. I was taken by surprise, but I was able to get an insurance quote today, and confirm that my garage has the proper wiring to support a 240V outlet, so I finalized this afternoon. It said my delivery estimate was Feb/March, but I'm skeptical of that, given my high reservation number.
I debated quite a bit on the tech package and the color (black or grey), but in the end I decided on Black, and opted to skip the tech package.
Black, 85 kWh, Active Air Suspension, Panoramic Roof, and Black Leather with Obeche Wood Gloss
