Nothing.
Great all rounder, but definitely would not leave a Golf GTI 8/16v on the road (I've owned all 3).
Mine was well modified but gets a little boring when driving hard on country roads. Lowering it puts it on tracks, and a set of 17" makes it look like the mutts nutz. If you don't drive too hard buy it!
Mine wipes the floor with a standard Golf GTi and is not far behind a Golf V6
So there... and they sound far nicer.
