I picked up the (new for me) Berlina today and apart from the vertical plastic side piece of the centre console trim facing the passenger seat falling out of place, everything else seems OK. I'm thinking of getting mud flaps and am wondering how hard they are to put on. Do you have to take the wheels off to do it? The selling Holden dealer told me $180 fitted and I said no thanks. I can buy them at the local dealer for about $91 for a set of fronts & rears, so that would make labour about $90 also. How many hours do they allow for $90 labour?
