where to get them

 
 i was thinking bout changing my a63.0 mirrors to the rs6 mirror the chrome or grey finish
but have no idea where to get them from'
if someone can post a site w/o saying ebay would be helpful 

autozone

um I would say ebay.de, or mabye google wold have the answer, I'm not really surem but I know ebay.de would have them

well.....i was gonna say 
AeUTbOZaONyE
 
surely there is some place to get that.  don't we need to know what year your car is?  where have you looked so far?  and yeah...google is the answer to everything.
...and maybe you'ld have more luck posting this in the A6 section.  maybe someone there has switched out their mirrors.
 
as you can see in my sig, my s4 has chrome mirrors.  don't know if they would fit your car or not.

You could always go to a dealership but it's gonna cost you the equivalent of your property taxes.

thanx, an my car iz a 02 3.0Q

stealership, ebay, or google are the general possibilities..........then again, you could always buy an RS6?

Scroll half way down and there you go. Price seems decent enough.
