Not really an A3/S3 related post but i wanted to see if anyone else gets pissed off by this. Perfect example this morning on the M27 i was following a 57 plate Range Rover with a full Kahn bodykit so not a cheap car but everytime he put his foot down a large cloud of black smoke would come out. Now not got anything against people having diesel cars but why do they smoke so much?? How do they pass emisions tests when they produce so much obvious emmisions??
