When I got mine in 10-14, I totally lucked out because I got the AP1.0. No charge at all. Not even activation. I bought just about the top of everything and paid 131K before rebates. I thought that was high...Yes, the 100 has a lot more power and a nice bump in range. But I am totally happy with what I have and don't honestly feel like it's obsolete after these two years for me.
@luvnMyTS makes a great point about the extra capacity not being a must have unless it allows us to skip a supercharger. Since I have an 85 battery, a 100 might allow me to do that. But for somewhere in the range of 20-30K more, depending on options? Not for me.
I really did worry that I would buy the car and I would regret it shortly after with the updates. I think that if I did not get AP1.0, I would be REALLY bummed. So I do consider myself very lucky. All by total chance. Certainly not by clean living!
