I think your statements are a bit over the top, Chow did an amazing Review, you can tell it was 'from the hip' and not scripted (i like that, I hate it when it seems like someone is reading off a teleprompter in monotone...).
And to your statement about the savings in Gasoline, for every single person out there, it's different. Some people drive Hummer's, some drive Civics, some drive Leaf's... I personally HATE the 'estimated $10,000 Gas savings' on the calculator, I think the entire Design Studio could use a remake. Seems too plain, too, small.. Almost resembles other car manufacturer sites, which I think is disgusting and TM should distance themselves from that style.
Make the studio completely open, have the Model S always in the field-of-view as you add/subtract the Option's you want. Maybe it's just me, but I feel TM should boast the beauty of their vehicles in their design studio. Hell, might even push those on the fence over and make a sale, just from the layout/look of the design studio!
