Hi all I am currently looking at purchasing my first Audi. I have always owned a VW and think its time for me to trade up. At the moment I am torn between the Audi S3 and Audi A4 2.0 TFSI. Would you guys be able to give me some pointers? Like how much you pay for insurance, Road Tax and MOT. Also running costs of the cars that you may already have. Thanks for your help Nirmie
