Just been doing some research. Numbers on the 08 models suggest the WRX and the STI both fall below the 255 g per km mark, which means they'll avoid this new tax hike. Can't get a definite on the earlier models, but think they're also below that. It's not by more than a bawhair though, so if they lower that number next year by even 10 or 15g we'll be screwed!
Petrol duty increase been postponed a few months too. But OPEC are still pumping us (pardon the pun) something awful anyway. What's another 2p in the equation when we're already paying so much.
