Ok so I have had my 58 plate 170 TDI A3 for about a month anddddddd.... I am bored. Thinking about getting me a facelifted S3 (58 plate) and I was wondering if I could get some feedback from S3 owners with regards to economy when town driving, economy when on a long motorway run, common problems with the car, etc. Any help would be appreciated. Thank you.
