The problem is if you don't like American muscle, it rules out pretty much every single car I listed. They are all the same style. So people that aren't fans of that style will hate them.
And I have a job where I drive these cars around all day. They aren't bad, but they aren't anything amazing either. I probably drive a few new Camaros every week and they are just ok.
If you were driving Challenger SRT8's and/or Mustang Cobra Shelby 500's around all day, and weren't impressed, you must have been driving them like my mom. I drove that Shelby this past summer: crazy, crazy fast, and handling to match.
I'm guessing you were driving the SXT's/V6's.
