Hi,
Does anyone know of a good site to buy a front grille for a 2007 S6? I want to get the RS6 version.
Someone hit my front end and cracked mine.
Thanks
eBay 
otherwise if you need another S6 grill I could sell you my OEM cheap.
seen them on ebay. Time for a better one.
I’d go through eBay. Even OEM grills are made of hard plastic. Should run you around $100-150 for a new RS6 grill.
Got my CF RS6 grill via ebay… It was a pain to find though since I got one that was CF instead of the normal one, but either way. www.ebay.de is your best bet.
I went the cheap route and got one for $88 off of amazon…
i went with an ebay one. installed the grille, but the car is still in pieces 
can upload a picture probably on saturday.
“Matte Blk RS Honeycomb Mesh Front Bumper Grill Grille+Logo Base 08-11 Audi A6/S6”
requires a little bit of DIY - the posts are not drilled and tapped and you will need bolts (I think I used 4mm? will have to check).
For such little money a grill can really change the look of the car for the better.
Remember to pickup some flat black spray paint to black out the crash bar under the bumper or it’ll peek through in a couple spots.
the Chrome on the stock grill was bubbling in spots on mine so it had to go.
