Just received my invitation to configure earlier today. I am #13,541 and have a red 85 KW design in my Tesla online garage. Was not expecting to get this invitation so soon. Will be thinking a lot about this in the coming weeks. I am considering changing to a 40KW battery. I am worried about rapidly evolving batteries that make the current ones obsolete in just a few years. Then I will want new lighter more efficient and longer life batteries, but I will feel stuck with an $80K car that is now old technology. I own a 2011 Zero Motorcycle, that I dearly love, but it is really old technology when compared to the 2013 models and as a result the older bike is almost worthless, so I will run keep it until I get my $10K of value.
On the other hand, if I don't go for the 85KW, road trips in the Tesla and super charging with solar will be out of the question. My general experience is that going with the lowest end of the offering is usually a mistake that I later regret.
What to do?
