There is no sense in worrying about, or pondering over what this Vette might be like. Let them build it first, then let the car magazines test it, and lets see if it lives up to the hype. Until then, keep driving and enjoying the best thing around, your Viper.
If they actually build this car, and it really turns out to be a Ferrari/Viper/Porsche ******, well, then, thats a different story. At that time, after its introduction, I would then weigh the appearance, power, and cost issues. But until then, its just a pipe dream.
