I am selling my S4 grill as I just received my OEM RS4 grill. The grill doesn't come with the S4 badge but you can get one of those for $7 from ebay.
The black plastic could be refreshed a bit to get it back to dark black as it is faded a bit but absolutely nothing broken on the grill, all tabs are there and the chrome rings and trim are in perfect shape.
Price: $40 obo.
I am in San Jose but also work in Sunnyvale.
