@nehcrut - Thanks! I didn't know that about KBB and will definitely check it out. I was already planning to get additional quotes, but that may simplify things.
(I also am using the Tesla 2 week appraisal window for the trade-in as a way to check-in and hopefully get more information about my X delivery).
I think your misunderstanding the 14 day trade in window. My rep explained to me how that works. You have 14 days and 500 miles from when they make the offer to you to buy your vehicle to accept it. For instance, my vehicle was appraised and inspected last week. and I am going to accept the trade in offer this week. But I just ordered a model X and am expecting delivery in September.
