The kicker is "once you get a VIN"
I did the trade in valuation at the time of ordering a new vehicle (when one would think to trade in their current vehicle.) It could literally be 2 additional months before being assigned a VIN. And no one knows what the used car market will look like in October.
I suspect that many people will be trading in their Teslas, so with an increase in used vehicles poured back into the market, what obligation would Tesla have for honoring a crazy value given in July?
@BPeter what are you planning to order & did you already get a VIN assigned?
