I think the company is over-valued and has been for a long time. They were in the crapper not too long ago; though they apparently have paid back their loans fairly quickly (I'm astonished at that, btw), I don't think their car business is sustainable. I see Model S's on the road more than I would have expected. But you can sell only so many $65k+ electric cars, I'd suspect that market is probably already near saturation. They're going to need to make cheaper and more-affordable cars if they want their business to continue to grow.
