I'm in San Diego and needed a new car but thought the MY was getting overpriced. I woke up on Friday the 13th to see the massive price cut and $7,500 tax incentive, so I quickly placed an order by 8 am. At the time of the order, it estimated my delivery between January and March. I was assigned a VIN just 2 days later (Sunday) and they were willing to deliver direct to my house today (Tuesday), but I pushed it out to Friday. I'm suspecting there was a mad rush of orders placed over the last five days, so it's really hard to know how long your wait will be with a backlog of orders. I already have Tesla Solar and a Model 3 and also said I was paying in cash, so I can't help but wonder if perhaps that gave me some priority?
I should also add that shortly after I placed my custom order, I looked at local inventory and there were only a few vehicles but one was the exact same vehicle I ordered. A couple hours later it was gone, perhaps Tesla just assigned it to me?
I believe you have 7 days to schedule delivery after a VIN is assigned. If you think you can get a loan in place within a week, perhaps just wait? Or if you are like me and only want the car if you get the full tax incentive before 3/31, you are probably safe to start the 60-day window in a couple week (very end of January).
