Depends what mood I'm in and what the weather's like - if it's hot I'll have the windows down, which kind of drowns out the radio anyway so it'll be switched off. It is often quite nice to just listen to the V6 though - not a feeling I've had in any other car.
Mine is my first alfa too, I prefer listening to the engine, which I have never done with any of the cars I owned in the past. Although it's only a 1.6 engine, it sounds great when the engine is over 3500 rpm. I engoy revving it every time.
I'd rather listen to anything rather than radio 1. Do these people really think I give a gnats chuff which nightclub some drongo from Huddersfield goes to on a saturday night. (no offence Huddersfield)
