it's a UK thing? as i never had this in Australia (they racing with BIG V8) and it's personal for me a big disadvantage of having a Subaru, even with my N/A Forester :o
i just let them go as i have no interest in big exhausts, turbo engines, big tires etc. i have my Subaru because their reliability , driveability, safety, 4x4 and i like the SG shape.
btw, the moment they take me over and don't see a scope on the hood they bugger off -_-
