Driven a E92 M3 6 MT I can say it was the wrong choice.
The M-DCT with shorter gearing was a much better ride then the too long geared 6MT
It`s a good thing BMW let the customers decide what they think is right for their way of driving fun.
I only do hope this time BMW does a better job on the M4 6MT
Either way, choose your poison
But choose wisely
