My choices would be...
Fiat 500 AbarthS

- Because its mental
A3 2.0L tdi Sportback - Because its comfortable an imho a good looking car
Scirocco TDi DSG - It possibly the best looking car in that genre
Seat Leon FR - Because treacle has one and its an S3 is a spanish body
Base range XF - BEcause you can
Vovlo S40/S60 T5 - Nice solid cars
Insignia - Great looking car with very good trim and nice to drive all day every day
I would say an a4 but the current one is horrible, if you like the old shape then the Seat Exilio (Or whatever its called)
