Well, some people want all the options, some people want strippers. Let's see, maybe they'll have:
R/T = bare bones fast
R/T / SE = Fast with options
SRT = REALLY FAST
SRT / SE = REALLY FAST and comfy.
At any rate, I can't wait to see this car in person. I know there are going to be some changes here and there. But all it has to do is remain relatively close to the concept to be awesome.
