Funny how they call it wasteful... I get 24 mpg in suburban driving with easy cruising and brisk acceleration.
And they say it's useless in snow or rain, yet I've had mine in plenty of both, on the Brembo-issued Pirellis, and I haven't wrapped it around a tree yet.
It's comparative against others in the 10 best. I've always said my 12 GT is, "rude, crude and socially unacceptable, but I LOVE it"!
