Dave, I'd like to know the format / process regarding final payment as it related to your delivery email.
Did Tesla call and tell you that your Model S is ready for delivery and we need a check or wire? Or, was it more along the line of here's your delivery date as long as payment is received by xx?
I just went through it a few days ago, so I think I can explain:
1. I got an email from Tesla HQ asking that I call a Product Specialist in Palo Alto.
2. He asked me a number of questions about my delivery requirements, registration issues, double checked the configuration, and after all questions were answered, sent me a 12-page "purchase paperwork packet" (in pdf). It was also provided using the DocuSign system. The turnaround between phone conversation and paperwork arrival took about 18 hours because another department completes the paperwork.
3. I electronically signed the paperwork and also printed a copy, wrote out my check for the balance (a personal check is fine, but you can also use EFT if you'd like), and fedexed the paperwork and the check to Palo Alto (TM gives you their fedex number to use).
4. After receipt of the check, the Model S is loaded on a truck for cross country delivery (I'm in Sofla). I've been told that the truck will make a number of stops as it moves across the US. I have not gotten hard confirmation that my vehicle is currently in transit (my "delivery specialist" in Dania Beach is working on it).
That's it. Relatively simple, no hiccups ... now, on to delivery.
