No one knows?
Trying to determine what edition B7 S4 my cousin has, im guessing it is the 25th AE although it does not have those wheels nor does it say "... of 250" next the gearbox. However it does have the CF front lip & trunk lip. Also has the CF interior trims and came with a quad tips exhaust.
here are a couple of pictures maybe you guys will know.
My apologies for the horrible pictures but they are all i have, hopefully they are enough for you guys to determine what it is.
That was the Sport Appearance Package that was offered by A.o.A. The car is basically an S4 with the DTM package optics from Europe, also used on the S4 25quattro in the USA.
Here's a pic of a press car we drove back when these were new.
The kit is probably most easily identified by the vents on the sides of the bumpers but the really cool part were the carbon fiber lip and decklid spoiler.
