7 speed DCT in '12 135i?
I am looking at buying a used 135i coupe. I test drove an M3 with the 7 speed and was really impressed with the transmission (not so much the lack of torque, however). Do all '12 135i come with a 7 speed auto/manual or was that an option? Also, any new opinions on going N54 vs N55 route if I plan to run the car with additional boost and MAYBE an upgraded turbo kit?
