I think the "healthiest" way to order a Tesla is take the targeted delivery date range with a grain of salt, make sure you have a reliable car, and wait to an email, call or text. PERIOD.
The unhealthiest way, which I think I mastered, is to check my account status when I wake up, go to sleep, and am bored during the day, and for extra punishment, come on these forums (where I learn a lot) but also get my hopes crushed, and vicariously live the deliveries and cancellations of the members, with some photos and videos and reviews thrown in for that extra dollop of torture.
Of course, I wouldn't have it any other way!
(I've seriously considered a mental health break - it's just a friggin car - about my 20th if you count what I've gotten my wife, kids, etc.) but dang, it's to be MY car - and though not my most expensive, by far my most technologically advanced and best performance.
In short, I want this beast. Okay, end of musings and foaming at the mouth.
