Unfortunately, the model 3 isn't scheduled to come out until end of 2017 (if that holds true) and my lease runs out in March of 2017 so... gonna have to wait until the round after this coming one (generally lease for 3 years at a time).
But if it was coming out sooner and it's visually appealing - yes, I'd have probably put down a deposit tonight. Assuming it's not god awful ugly; which I can't imagine it will be.
