Any photos would be appreciated. Also, is it just me, or do the s line wheels have a dull finish?

FWIW, there's a pic on the Audicanada web site. And the S-Line A6 I've seen here in Calgary had 5-spoke rims similar to the RS6 19" rims, but without the "bevelling". In other words, the spoke "faces" were flat, not bevelled.

BTW: It's only offered as an option on the 4.2 A6.

HTH.
