In my opinion, a 2010 LC200 would likely not be accepted by BAT for auction. It is nowhere near old enough, rare enough or special enough. BAT is very selective about what they accept for auction. If you go to the Bring a Trailer website, you can easily search current and completed Landcruiser auctions and you will see that 200 Series Landcruisers are not in the mix. You could also try the usual online sources: ebay, FB Marketplace, Cars.com, autotrader.com, cargurus.com, etc. As for CarMax, they currently have 4 Landcruisers for sale nationwide, and the oldest is a 2017. I suspect CarMax might well pass on a ten year old LC just based on age, and would certainly come nowhere near the high $30k range if they did offer to buy it from you. @JohnJB 's NADA numbers seem about right. Good luck.
