never liked the chrome grill on the NG900 and OG9-3s.. too cheap looking and the chrome was peeling off of mine. I tried painting it black, but it looked terrible against the white. Painting it all white just made it blend in.
instead I mated the chrome centre bar from a new 9-5 to the original grill. I had to cut out the centre bar of my grill and fill the holes, and then cut and glue the mounting points from 9-5 grill into mine.. new paint, and the car looks even more modern.
