Last car: 2008 E92 M3 6-speed - loved it. Awesome car, all the control and fun of a stick shift.
Current car: 2011 E92 M3 M-DCT - feels like a different, better car. It does everything well. It genuinely feels like this car was designed for DCT.
I do miss stick sometimes, but all in all it's definetly an upgrade over 6MT.
