Hey Drew, I'm the guy that, in an earlier post, mentioned that you should make sure your insurance company knew that your car was a Model 3 Performance, and offered the advice of not muddying the waters by trying to tell your insurance company the difference between a LR AWD, your "stealth" Performance, and a standard Model 3 Performance. While I still stick by that, there is another option you might want to consider...
While all Teslas have done well regarding value retention, the "stealth" Performance models have done *very* well. If they are allowing you to submit cars to them to look at to determine valuation, it might be worth your time to specifically look for 2020 "stealth" Performance vehicles. They have retained their value so well that for a short period of time, my (used) 2019 stealth was actually worth more than what I paid for it! I haven't looked at prices recently to determine if that's still the case (I can't imagine it is), but I do know that overall, the "stealth" vehicles have retained more of their original value than other models.
If you can somehow convince your insurance company of this, you might end up coming out better in the long run.
I'm sure that there are more than a couple of us that are really interested in how this works out for you... keep us posted?
I'm sure sorry you lost your unicorn car. Makes me sick just thinking about it. Your car was my first color choice, too. But since I slept on it, it got sold out from under me (12 hours!), and I had to settle on blue.
