Unfortunately, as mentioned, Tesla 404'd those links. I'm just not sure why I'd believe this data is correct. At least when Tesla was backlogged for US orders, VINs weren't assigned until a few days before delivery. As another commenter pointed out, they have a number of systems that seem to not agree with each other. The twitter thread's mocking "who wants to buy a flooded car" post is written as if he's caught some nefarious plan to sell an un-saleable car, when, in fact, it just seems to be further evidence that the data is garbage. Not to say it's not legitimate, just that it's not GOOD.
It just seems so silly for this guy to suggest that Tesla is a garbage incompetent company on the verge of perennial bankruptcy, but some web portal is clearly the Source of Truth of all inventory data, and couldn't possibly be in the sort of disarray they accuse the rest of the company of being.
