Just sharing in case anyone waiting is wondering:
Ordered my Tesla Model Y back in July on July 22, 2021. Estimated delivery date was Mid to Late October when I placed the order back in July. Eventually my account status page updated the estimated delivery to Late October to early November, and then eventually the estimated delivery date disappeared completely.
On November 3, 2021 I received a notification my Tesla Model Y was ready for pickup, and my pickup appointment was the following day on November 4, 2021 at noon. (Fremont Factory pickup.) At the time of my notification on November 3rd is when I received my VIN, and so had about 24 hours to get my insurance, digital agreements, and payment completed. It was a bit of a rush, but all ended up working out well and I drove off with my Model Y the next day on November 4th. I'm now just a few days into being part of this Tesla fam (hi! everyone), so am just getting the hang of things.
Sharing my dates because for a while in October I was just wondering if it was normal to not receive the VIN at all in the expected delivery month, though my friends working at Tesla basically told me the estimated delivery times are notorious for being inaccurate. I didn't think I would only have 24 hrs notice to get everything in order, so just a heads up. Insurance is easy to add and agreements take just a few mins to sign, but the payment is a bank connection that withdraws from your account. (Or alternatively requires a cashier's check upon arrival/pickup.) So don't transfer/convert all of your cash into assets that cannot be liquidated within the same day.
