I'm looking to upgrade the lights on my 2008 mk7. The ones on it at the mo are halogens and are really cloudy. I was thinking about putting factory xenon units in. How good are the factory xenon projectors? Or am I better of spending €300ish retro fitting projectors and polishing my leneses? I've done retrofits before that that side I'm not bothered with, but if the factory ones are decent it would save me the hassel.
