Tech package is not optional, for me anyway. That's simple.
I'm not sure I'd get the twin chargers. They would only be useful to me if I wanted to charge away from home using a >40A J1772 station or Roadster HPC with an adapter. Supercharging doesn't need it, and I don't care about charging fast at home - in fact, I prefer slow charging at home to conserve battery lifer
What makes me consider performance is the extra zip and the advantage of cornering in the 21" wheels. I have hopes of playing with it a little bit someday.
Although I like the look of the red pin stripe and the CF dash trim, those don't sell me. And neither does the "spoiler."
But dark 21"s on a dolphin gray Model S look killer.
