Just taken another pic of it for you (side on) so you can see the wheels more clearly. My understanding of the S-line options in the UK is they come as standard with the 5 spoke 18" S-Line wheels, on 225's 18", 40's.
For 17" wheels, you would have to order a normal Sport version. All my Audi's have had 18" wheels with Sport suspension, so haven't noticed much difference between them. The 225's are slightly ligher on the sterring than the 235's I had on my A4 though.
Reckon the S-line wheels make the car look awesone though, and alot less common than the Sport 17". /ubbthreads/images/graemlins/groovy.gif
