It maybe sightly less bulking looking once the cladding comes off. But I wouldn't expect it be like S2000 low, or like the concept. Even the 86's fender looks high from the same POV.
I for one love the double-bubble roof. The exhaust tips could be slightly larger, but the ones on the spy car isn't that large to start with. The only thing I would point out is that the the fenders are a little higher on the prototype.
That or a really good guesser. Told us weeks in advance that the car should be 380hp+; later learned its being reported at 385hp. Also said 2 weeks before TMS that nothing will be unveiled.
This could have gone into either one of these two Gazoo/GRMN threads.
