"finallybuying", I completely agree with you. I am one of those guests, and I've been snooping around here for quite some time!
My main concern, being a total gearhead, is not knowing ANYTHING about what Tesla plans to do (as "ArtInCt" mentioned, Tesla makes changes/updates completely unannounced).
I find Tesla's secrecy to be mystifying....
Finally making the jump to electric, I've been leasing BMW's for at least the last 15 years. The greatest aspect of the automotive industry, for a diehard like myself, is knowing what changes lie ahead, when it comes to things like new tech, new engines, facelifts, upcoming trim changes, options, platform modifications, etc., etc.
I've purposely prolonged my past purchases in anticipation of these changes...that unfortunately is not an option with Tesla.
The most disconcerting aspect of all of this, again for me at least, is I'm about to spend $90k on a vehicle that may receive major hardware or cosmetic changes 6 months from now, and I have absolutely no way of knowing, other than forum rumors, and retracted Tweets from the company's founder!!!!!
When all is said and done, the end product is not only fabulous, but now well established and worth the investment. I feel that as a consumer however, I'm (selfishly) entitled to know what changes are on the near or distant horizon.
I'll be honest in saying that if I were to be leasing another $30k Volt (which is the car that got my wife and I hooked in the first place), I wouldn't care as much, but for a $90k + investment, I'm somewhat more concerned.
I realize I'm probably in the car-obsessed minority here, but I would like my investment to remain within the current product cycle for at least 3-4 years...
