Actually what the title of this thread should be is "Current owners just got robbed by Tesla".
This is possibly the worst thing I've ever seen any company do to existing customers. I'm going to talk in my local currency, imagine you just took delivery of a $250,000 2018/19 P100D Model S (that was our local price two weeks ago), then you wake up to the news that the exact same car is now $165,000 (the Model-X is even worse, an $85,000 price drop), not because of anything else but Tesla's own decision to drastically drop the price - regardless of why they did it, they did it.
I understand prices fluctuate (usually up), but this is not a fluctuation, this is total disregard for anyone that purchased an S or X in the last two years because now their cars through normal depreciation should still be selling for more than a brand new one, but they just tanked.
It's bad enough that Telsa can't manage to be able to release software where everything actually works frustrating the heck of our owners, then to devalue our cars that much overnight is just another kick in the bollocks.
Before my warranty expires I will be selling this car because, well, why would you own a Tesla out of warranty!, but I'm 100% sure I'll not give them one more cent after they've pulled this stunt.
