I think Tesla used to shuffle cars to a few locations (Manheim Auto auctions?) for basic cleaning and posting of pictures and stuff... maybe now the local service centers are handling it initially as long as they can clear the inventory right away? I always thought it was crazy that Tesla used a 3rd party for any amount of work since those cars usually sold within 24 to 48 hours of showing up in their inventory, especially since most were low mileage (less than 20k) and probably in pretty good condition. Basically just need washed, photographed, and sold...
