My suggestion would be to chill and do whatever you must to get off the emotional rollercoaster. Buying a new car should be fun, not a source of great anxiety. I went through this whole thing myself once before with the original Roadster, where I put down the $50,000 deposit, and I waited, and I followed every scrap of news, and there were delays, and rumors, and more delays, and transmissions were breaking, and the CEO (Eberhard) was fired, and some guy we'd never heard of named "Musk" took over, and after a year and a half I was so exhausted by the whole affair that I got my deposit back. And then I was done with Tesla for a while.
A few years later, after all the drama was over, and I had recovered from all that, I realized that I did actually still want one. I found one on eBay and had it shipped to me, and it's been great.
That whole experience is why I haven't put down a deposit on the new Roadster. I'm just gonna keep my distance and not get too deeply wrapped up in it this time around. When there's more info, when it's looking closer and more real, then I'll get serious about it.
Until then. . . Have you thought about getting another car to tide you over? Something fun? Something that you can have right now and know exactly what you're getting. There's nothing else like the Roadster, but there certainly are other vehicles of various types that may be worth looking at. I've pondered various ideas from a used Corvette or a Cadillac XLR-V to a new (and recently updated!) Model S. But, well, I do have the old Roadster here already, and it still has a bit of life left in it.
