They have already partnered with some auction house reading elsewhere. Jan 5, taking my daughter back to college two loaded car carriers all Tesla AP-1 MX-M3 cars headed North I assume to northern location to be auctioned off. The Tesla lots down here are bulging with cars they cannot sell.
There are only so many they can sell online, sight-unseen. To sell outside the Tesla enthusiast crowd, they need retail space and that's probably a headache they don't want at this point. That may change someday, after all there's supposed to be good money in used vehicle sales.
