CGX car nut:

I remain undecided between the manual or PDK .

PDK every time. Faster, more economical and better in every concievable way. There is no reason not to specify it. Make sure you order the sport design "paddle" wheel with it though and sport chrono.

Really tough noice to be honest. I can see why anyone would chose either or. The clear choice for me is the car itself, I haven't driven it but it terms of performance for $, this is the best car Porsche makes today.
