I'd ask the same thing lol.
I don't know really, always fancied a bmw and it would have saved me a fortune if I'd have done it before the r lol.
As soon as I drove it I could see the difference staight away. It may be second slower to 60 but it just felt right driving it, sounds weird but I just felt comfortable behind the wheel. Find it very refined and very relaxing to drive. Always felt like I had to rag the r to get the best out of it being a hot hatch but with the bmw it's just easy to drive. No aggression and no sound actuator thank God.
