I think when you hear the name Clubsport you think of stripped back, race-inspired Porsches. I don't think VW has never used the name before they made the ED40/CS S. It's just marketing. Like the TCR that had nothing to do with the touring car race series apart from the terrible side decals!
I do think the Mk8 CS is what a GTI should be like. Decent power, decent-sounding and looking exhaust, beefy brakes, larger but not stupid spoiler. And with prices already from £32k, IMO I'm not sure why you would opt for a normal GTI. Just a shame about the 18" wheels but guess that's an easy fix. I'd like to see a Reflex Silver CS on 19" Prets...
