Look I'm just over this car- I can't get any online vendor to give me a quote for trade in, not even Tesla! And I'm over it all- I just want to be done and go back to my 2008 Santa Fe (kidding-kind of)
Try Vroom, Carvana, CarMax.
There was another thread that showed the MMR auction numbers ($67K for MYLR)... which are $3K-4K above what a trade-in or sale would fetch from peons like us.
Since you have a 7 seater with white interior and MSM.. my guess is $67K and at auction would fetch $71K or more. Absolutely lowest would be $63K that I would take. I traded my white MYLR with 20" for $60K for a Mach-E (long story - I'm moving back to Tesla in 2022) 3 weeks ago. The dealer entered my info into some auction system and gave me that number.. it was a tad low to me but I saved $3K in taxes in FL.
Here's what I got from another dealer (again much lower trim than yours)
