I understood it that PakBMW was talking about the mesh grills in the bumper/fender but as said before the cost seems high. I know a paint shop will tell you they are taking the bumper fender off but not sure if you really need to. Could be worth getting down on the floor and having a look. If you are able to get the mesh of and deliver to the paint shop than the cost shoud drop like a stone.
