The line may keep getting longer because each year's demand is more than the production. When you do want to get a Model 3, you may have to wait another few years. The deposit amount is so small, I think it's safer just reserve first. For the stock price, I think there is a good chance to hit $600 by 2020.Great point. As a potential first time buyer in the UK, I thought I'd be waiting until 2020. So I have decided not to reserve online. The $1,000 deposit not spent will probably return good gains in TSLA, and all I lose is the pride of owning a desirable and scarce product a little sooner.
