Hate all you want... If I could sell my Model S without losing $30k with 9 months of ownership I would. The depreciation on these vehicles is worse than any car I have ever owned. When the Model 3's are readily available the Model S will plummet even further and faster.
That's why I bought a used one, It is "new to me" I get the tech, The first owner took the $50+K depreciation hit, and at least "for now" the CPO prices are being supported by the next wave of adopters (like myself) who are finding value at current CPO price points slowing the hockey stick depreciation curve.
A new car has NEVER been a good investment. They are "at the end of the day" a transportation tool.
