To me the question is simply a matter of what's more important to you. Do you want to save money with free Supercharging, or do you want the latest technology? For me it's a new brainer. I'm a technology geek and always strive for the latest and greatest that I can afford. Even though I never imagined owning a $100k car, I never factored in the cost of charging to the purchasing decision. If you're more budget conscious or don't care as much about the latest technology, the free charging may be right for you.
