As you have noticed in the past, the 991.1 GT3 is already too fast a car to fully use on the streets, so for someone who prefers manual shifting, I don't think the trade-off in performance is a huge concern.  For street driving.  That said, I would still go PDK on this car because it suits the engine so well and because on a car with this kind of speed, I want to be fully focused on the other inputs.  On my GT4, I would not get PDK even if offered because the acceleration is not explosive enough.  I am on my dealer's list for the next GT4 and will consider PDK for that car.

Will be interesting to see if people put their money where their mouth is re manual.  U.S. manual sales should be much higher than ROW.
