Aaaaaand it happened. My Vin disappeared and sure enough when I call I am told my car was "matched to someone closer to it's location" and I will be "contacted to reschedule delivery". &$@!
When you finally do get your car, make sure to pay with a personal check, and make sure that check bounces. When Tesla contacts you to resolve the matter, tell them "I'm so sorry, but your payment has been matched to someone who needs the money more than you do. You will be contacted to reschedule payment at some point in the future. Thanks for your patience!"
