it's one or the other. you either hit 12s or you get 33mpg. they don't have a car (that i know of) that can pull off both. remember, i didn't go looking for this, it came here on its own legs.
and i love a good pissing match every once in a while.
p.s. i still know of only one person who has a modded V6 that runs better than most V8s, but he isn't gettting 33mpg, either.
