Manuals are good for many reasons outside of racing.
-better mpg
-better control over the car in general
*less corrective braking needed
*more control in snow/ice
-manuals last longer than automatica, clutches are cheap trannies are not
-more fun/interesting and more involved to drive, making you pay attention to the road more and in turn making you into a better driver, unlike the typical lazy non-skilled auto driver
-real men drive a stick
Agree with all those except the MPG claim... That's all about how you drive and when you change up
As for the 'real men drive a stick', I think it's more like 'real men can drive a stick'. I can drive manual, but choose to drive auto as I live in a super-super congested big city and can't be bothered using the clutch every three seconds.
As for GT, I'm in the process of teaching myself manual... Am finding it tricky with the DS3 though...
