So, for anyone that's interested, I've got a MSM MYP with no tow/no FSD that had an estimated delivery date of December 11-31st. I called up and explained my desire to delay delivery and they pushed it 90 days out. The earliest* date they will now assign me a VIN is February 27, 2022. I have NO idea how they concluded that was 90 days out.... but that's the date I was given.
My main reason for delaying is to a) make sure I am eligible for the tax refund IF it passes and b) perhaps get lucky and delay long-enough to get any early year updates, such as new door trim (if indeed any new updates are rolled out, which may not happen). Doubt I'll get a car with 4680s though, almost certain not to imo.... but not impossible.
I plan to order a second vehicle in December or January if the price hasn't gone up by more than $2,000 and put that on a 90 day hold as well. My goal with that is to have a second optional date that is in the mid-late April timeframe... just in case the 4680s do drop and it looks like my current order is going to miss assignment by less than a month. A $250 gamble that seems worth it.
Point being... my main reason for posting... is that for folks who are wanting to delay delivery until 2022, it appears all you need to do is call customer service and they will put it on a temporary hold for you.
