Tesla don’t need to sell cars to MB they just keep up with demand as it is. This question does raise a good point though , would a 3 or better still a Y be a good addition to the scheme? Taking into account the size of the Y and charge network not to mention the residual values would probably be better than anything on the scheme I would say it would work well. Tesla could afford a decent discount and if they threw in free supercharger access and a Tesla wall box the free publicity would be totally worth it. I’d have one I think, what about anyone else?
