My understanding is one can edit their order right up until it is assigned a VIN. Also, in talking to Tesla, because delivery advisors are so overwhelmed it may be that your notification of VIN assignment may be a week or more after VIN assignment.He suggested I call every week to check. I think I'll call once or twice a month instead. I still don't see how the math works on this. 420,000 reservations. About half are for SR so 210,000 for LR. I'd guess most RWDs have been delivered so, approx 100,000 AWD. At 5,000/wk that's 20 weeks or 5 months. Frankly, I hope I am wrong. I reserved Sept 3 last year. LR, AWD, PUP, FSD, Aero.
