Currently I am coming up against the January 1rst deadline. While I do not mind being a beta tester for small engineering gremlins and omissions (except parking sensors), large ones such as fogging, 12v problems, and charging malfunctions are a serious concern. Anything that turns the car into a very expensive paper weight is a real issue. I believe that Tesla will work diligently to address these "bugs" and a Model S six months from now will be a more refined car. Please do not mistake this post for bashing. I have definitely drunk the Kool Aid. I am just wondering if a little delayed gratification now will save a lot of frustration. For those that have taken delivery, any regrets not waiting?
