Honestly mate, the manual is LOADS better than the SMG....Less problematic, nicer to drive slowly when needed, Less of a boot floor issue, better resale values..(Because there better) Just out and out a better car to drive..............
SMG if you want to say.."Oh, i have paddle shift"..............Which will then be followed a few months later with...."My M3 is broke, its the SMG Pump/soliniod/boot floor"
Thats my view anyway mate
