having been around exotics and a few super cars and there aren't many out there, the SRT6 is not even close to being a super car. It's not unique enough, fast enough, or quite frankly pretty enough to be a super car. There are only a handful of super cars being made today. Now if your talking exotics which is what a Ferrari 458 or Lamborghini Aventadore is you're still way off.
Is it a sports car? yes.
Is it a fast car? well sort of.
Is it a great car, Definitely yes.
Is it an exotic or super car? Thats a laughable suggestion, but just to be polite, definitely not today or ever.
