Hey everyone I'm buying a new a3 black edition. Now i'm not sure which one to go for, initially i was keen to get the TDI 140 however, if that only comes with a single exhaust pipe then i ain't interested. I currently have a black s -line 1.6 which doesn't seem powerful at all. should i go for a tdi 170, or a 1.8t ?? i want something with considerable power difference to my car. I have also considered a 2.0tfsi but that might be too costly or bad on fuel???
