To me the sb with roof rails looks like a hearse and I could never think about buying one so good job that Audi brought out the saloon. Point of fact is that it doesn't share any body panels with the sb only the convertible, it also has a wider track and wheelbase, thus it should ride better. The comments about the wheel arches are true as they are bigger because, again along with the convertible, they are the only A3 that has them big enough to have 19" wheels fitted. There is one base colour the saloon looks good in and that is is white so I suggest looking at that colour too but all of the reds that Audi have seem to me to be the worst colours of the whole range.
I wouldn't judge the look of the car from my photo as the shadows make it look different than it did in the flesh. Hell who am I to have to defend what is the prettiest looking car in the whole A3 range and if it wasn't for the 'exclusivity' of the saloon I'd be sticking with my Ford..
