There is NO WAY I would make a final payment until the day of delivery or at delivery. I made my payment morning of delivery of inventory car. An hour later, they cancelled delivery entirely. I spent three weeks getting them to refund my money. There is no need or requirement to pay fully before delivery (except maybe in a few states).I got a vin and heard nothing from anyone for a week. I reach out to my SA and got generic reply number 3 that he could chose from to send back. Last night I finally got my please make your final payment and once I completed that there was already a pick up day and time set for me.
Tesla will try to bully you into it. Do not let them.
