I also went for the 6MTdespite the BMW salesman being very, very ambitious in convicing me of the ZF AT. I do also think that the AT is a better choice in many ways, speaking of efficiency and comfort.
But I bought this thing as a kind of sports car... I want to shift gears myself in that.
Havenīt regret it once in my 2,5 month ownership. Havenīt stalled it either
