i know the window sticker says 16 and 22, but what does it really get on the highway? a 6 speed on the highway has to do better than 22. anyone got any numbers for me? i'm looking into buying one, but its got to do better than 22 on the highway. i used to cruise with my 04 gt at 60 and get 30 mpg. i know a gt is no cobra by any means, but its got to do a bit better than 22.
