A3 Sportback S-LINE

Hi All,

I am considering placing an order for a new A3 Sportback 1.4 (140 ps) S-LINE with an SE suspension. Can anyone tell me about the ride of an S LINE WITH SE suspension as the dealership does not have one like this? Is this a suitable set up. I am very much much of a novice with cars, is there going to be a big difference between 17 and 18 inch wheels??

I really appreciate your help
thanks
Paul
