2013 BMW 1 Series Convertible 135i 2dr Convertible (3.0L 6cyl Turbo 6M)
Excellent car - mixed bag transmission
 This is my second 135i convertible, and I have over 20k on this car at the time of this review.  I was somewhat reluctant to order it with the then-new-to-the-135 7-speed dual-clutch transmission instead of the manual, but I was persuaded by the thought of the lightning-fast shifts and the advantage of being able to select between auto and manual modes.  The reality is that in manual mode, and even auto mode for fast acceleration, the transmission is brilliant.  But in stop-start, mundane "through the neighborhood" use (where you just want to leave it in auto-mode), the transmission is hesitant, clunky and confused.   In other words, where you most want it to be an automatic, it is wanting.
