Stick or no stick in a 6? Vote for what you have and where in your 6 series. Don't put what you'd get, or what you want, or what your friend's brother's cousin's ex roommate wanted to get.
Now that I have one on order, I wonder how many MTs there are out there. We had a 2009 Cayenne stick until recently, and it was one of a dozen or so in the US. Loved the confusion from valets- both trying to find the key and the surprise at finding an extra pedal.
