Just a quick moan (I've got nothing better to do today). I noticed that the alloys were getting very dirty very quickly so I decided to clean them and boy was it a job and a half. It seems the dealer had polished the wheels with some oily stuff and the brake dust was sticking to it instead of blowing off. It took me ages to get it off, and there is still an oily coating on the wheels. I suppose it'll wear of given time and a few washes.
