I have to admit that I am not 100% sure of the 3dr A3, but what I said already should be true for atleast the Sportback. And if not in the UK, atleast in Finland /ubbthreads/images/graemlins/smile.gif
The UK spec for the S-line seems to be a bit different than here anyway, since here you get 17" wheels even with the S-line, and you have the option to get 18" (for extra cost ofcourse)...
