I have the M340i touring and I love it.
I used to have an F30 335d and ever since having that I wanted a petrol since the diesel had no noise, just lots of torque and speed. What a difference in M340i! It feels more refined, faster, better handling and sounds amazing in my opinion. I want to get mine remapped using DMS in the UK. They claim to get the M340i to 470 bhp!
