I am intending buying the A3 Sportback in Sport trim - mainly for the climate control and Sat nav as standard. I am a bit worried about the "sports" seats however. Are they just different in trim or are they different in design and dimensions? I am interested in one thing only - comfort. Also, how can I put this delicately, my wife is somewhat bigger across the beam than me and I don't want a seat that is a bit more of a squeeze :-) Any thoughts would be welcomed.
