I'm not sure how it's a "fault" that they have so much margin across the cars. That's something other manufacturers can only dream of.It’s teslas fault they have such scope to reduce prices significantly though. BMW etc do not. That’s what’s killing used teslas. Moral of the story is don’t buy a Tesla. Second and last for me. Crazy company. Awful boss.
Unfortuately Tesla's only meaningful revenue stream is selling cars. Whatever they make from aftersales is surely negligible, given they don't even mandate servicing for warranty, etc. This means they are highly motivated to keep increasing volume, even if that means reducing the OTR price of the cars. Consequently it's people who actually buy the cars who suffer, as it stands to reason the greater the choice on the second hand market, the less likely any individual selling their car is going to get top money for theirs.
