I think everyone has already summarized why smg is awesome.
I like having to explain to people that the car does, in fact, have a clutch and is a full manual car, but just computer controlled, and hydraulically actuated. It blows people's minds. When they see the paddles on the steering wheel when they get in the car, they say they feel like they are in a race car. Whenever someone sits in my front seat, they say they feel like they are in a rocket ship because you're just hands to the wheel as you're blasting through gears. I think once my car gets too tired, I will buy another steel gray smg.
