The sound of a Prius. Oh, don't get me wrong, if one wishes to own one, more power to them; freedom is a wonderful thing. I'll just take the sound of a finely tuned, roaring V8 over something that sounds a Dust Buster.
My EcoBoost F-150 sounds like a sewing machine with its tiny little V6. And it will blow the doors off a Chevy Duramax all day long. Don't ask me how I know.
