Does anyone have an idea when Tesla will start selling certified, pre-Owned Model S'? While some of the loaner fleet that was purchased perhaps added a Tesla to an owner's fleet, and some were outright sales to people who couldn't wait through the ordering process, there have to be a number that replaced existing Model S'. I guess Tesla could be using those trade-ins as loaners for the time being, but at some moment that diminishes their approach to upselling to existing owners with top of the line loaners. I'd imagine there would be a CPO market pretty soon for Model S'. Thoughts?
