Heh... Tesla sends me an email saying that, if I want to ensure that I can get my hands on one of the new Model IIIs, I need to put a deposit on one, now.
Car is going to be unveiled tonight. Frankly, I don't buy - or pay to reserve a chance to buy - anything that I haven't seen yet. The fact that they're only expecting deliveries to start late next year - and then, only if I'm in California - and that signing up in the first half of 2016 is likely to maybe get me a car sometime in the second half of 2018... I gotta think, "sorry, no."
Even if I were someone who buys based just on a label, a lot can happen in a 2+ year period. You'd have to be a special kind of special to do that. I mean, I sorta understand it for the people who were looking to buy $100K+ cars - because, you're clearly buying an optional vehicle rather than a daily driver - but a car that's supposed to be priced in the daily-driver range? No. Just, no.
