same fuel consumption, just as refined but much much faster.

How did you manage 30mpg from the M3? I researched them as i was looking to buy but they were thousands more a year to own in running terms (servicing, parts etc) Decided i didnt want a car that meant i needed a few thousand in the bank for when (not if) something went wrong!
I find turbo engined cars are a little noisier mate, maybe you are just use to N/A engines?
