Has anyone ever had Tesla take back a trade in offer claiming it was a mistake. After several months of negotiation I received an acceptable trade in offer on my Model S, via e-mail, and placed an order for a Model 3 the same day. I had several e-mail exchanges with Tesla that included the trade in price. Now almost a week later, and with an estimated delivery date of next week, Tesla claims the trade in offer was a mistake and they can cancel my order.
