I think that some garages just dont get it.
I took my MKiv for some work doing on the brakes. When I walked round it three of the alloys had been damaged.

Not just little chips big gouges on the face of the alloy spokes. I went back in and spoke to the mechanic. Oh that he replied, We dropped a spanner on one and the other two fell over!!!!!!

Ye right. Lets just say, you were never going to miss the DEEP gouges in a million years. Why do they keep quiet??? It cost him more to fix the alloys than what I had paid for the work that was done.
Never went back there again. (It wasn't a main dealer.) Mind you as I have said in another post I got two sets damaged by a main dealer also...........
