several Tesla employees told me that VIN assignment means that the car configuration you ordered is somewhere in the build process. VIN numbers get assigned anywhere from the start of a build up to the end of the build. Fremont factory is turning out cars about every 8 mins, so by the time you check on it, the car may already be built.
OD 3/3 Model Y: Midnight silver/white interior, 5 seater Delivery 5/8-6/13 Last week I got a text: Delivery date was set for 3/29 but no VIN, but then pushed back to 5/1-11.
We were on vacation last week, so I did the Tesla Power of Attorney form for a friend to pickup the car for us. I took it to the local Tesla dealer and they were good with it. I got a cashiers check and gave it to my friend for payment. I provided my current insurance to the sales lady and she marked me down for insurance.
This morning I replied back to the phone number and asked why my date was pushed back. They said that I would be notified once a VIN is assigned and delivery schedule. Less then an hour later I saw in the Tesla app that a VIN was assigned. 5mins later, I got a text and email to schedule my delivery day. About an hour later I got a call from a guy at Tesla in Rocklin, CA verifying my configuration, payment option, trade-in, delivery day/time. He told me to have the cashiers check made out to Tesla Inc. Picking up the car Thursday 4/6.
