Contrats on the new estate, I've been enjoying my '11 E91 M-sport/6MT quite a bit. Jealous of all the engine availability across the pond. I was in the UK in February and had a 5-door 120d as a rental, loved the torque of that engine. Didn't much care for the RWD/summer tire combo though when going through a snowstorm around Doncaster and York though
I remember seeing quite a few 320d E91s about there, it seems like the right choice considering the fuel prices. If we had fuel priced at $9/gallon as you do, we'd be screaming a bit more for diesel.
Loved seeing all the F11 520d's around as well in the UK.
