I have a pair of brand new, never installed, virgin, not-a-scratch-on-them, perfect matte black side grilles for sale. I bought them 3-4 months ago but have not installed them and I don't plan to. I bought them new from Bimmer Performance Store for $89.95. Asking $60 + $5 FedEx Ground shipping with tracking and insurance in Continental US.

Please note: even though Bimmer Performance Store shows these with ///M logos installed, they do not include them. I do not have them, either. You will either have to re-use yours or buy new ones. I wrote to them about how their ad is mis-leading when I got these, but they never responded.
