Just an FYI if you're transferring more than $50k from Wealthfront via Plain it won't tell you, but the payment will bounce. I learned the hard way so you don't have to. I was scheduled to pick up my CT on 2/24 and made my downpayment through Wealthfront on 2/21. I got an email from Wealthfront...
From the time of configuring to delivery should be around 60-90 days. Most are happening within 60-70 days. Your time will come and all the time you waiting will fade away.
Tesla will take payment on delivery day, but I am just getting the payment stuff out of the way. I want to enjoy the CT and not deal with the money stuff on delivery day.
