For any Model S/X owners, how does Tesla handle trade-ins? Specifically: Is Tesla the one taking the trade and dealing with the paperwork, or do they employ a third party that works with you directly? When in the ordering process do you find out the value that they have assigned to your trade-in? Are they willing to negotiate on the trade-in price? Does the trade happen when you pick up your new Tesla, or is it more complicated? Every time I’ve chosen to do a trade-in instead of a direct sell, there has never been a wait between buying and receiving the new car (ie, the new car has always been in stock on the dealers lot), so the trade-in was always part of the negotiation process, and I would just leave the old car and drive away in the new car. With the Tesla approach of no negotiation and ordering online, I don’t understand where the trade fits in. Any direct experience with trade-ins would be greatly appreciated!
