I have a pair of OEM performance grilles that I don't need so I'm selling them. They retail for about $105-120 depending on where you buy them. I used them for about a month, but there are a couple minor scratches, that you can't really tell at all unless you examine them crazily. I didn't even notice them until I washed them and checked every part of the grilles in the light.
I will sell them for $50, Local preferred. Located at Southern California.
Here are a few pictures of them and with one of them on my car
