Also, they don't provide service/repair history, so you don't know what work has been done on the car.
However, given Tesla's "swap it" approach, it is less the ICE situation of "has this engine/ transmission had problems" and more "does this have a newer version of the DU/ pack/ MCU".
(I've never recieved service records for used car purchases before. What is anyone looking for with that information in a Tesla? )
I agree, they only care about new sales numbers, as the company's only goal is to publish better sales numbers keep the stock stable.
Just because Tesla owns the local showrooms/ service centers/ galleries does not mean the local people's actions align with corporate expectations and standards. If the manager is failing at that location, perhaps they need assistance, training, or replaced.
S/X production is close to maxed out, so there is no way to boost those sales numbers. The changeable numbers people care about are the 3 production ramp, and those buyers already exist (multiple levels deep).
