I bought my E60 from a BMW dealership a few months ago and there was a mesh grille in the opening on the rear bumper. It looked like it came that way from the factory. Recently, someone stole the mesh grille and the opening looks odd and out of place so I went to the dealer to order it, but they told me that it was probably an aftermarket item. After taking a closer look at M5 photos online, I was shocked to see that the parts guy was right, however, I also found a few posts on other message boards where a E60 M5 owner claimed there is a mesh grille available from the factory. Can anyone clarify this?
