I am shopping for a used Cayman on the internet, and have a question. I see one, two, or three buttons along the bottom of the center dash. I believe the first is used to raise and lower the rear wing. The cars with PASM appear to have three, wing, a picture of a shock, and the word sport. My question is what option do the cars with two buttons have?

 

Just two buttons are: PSM (stability control) and wing (raise/lower)

PASM adds a button (shock)
Sport Chrono adds a button (two buttons if it's a PDK car)
PSE (sport exhaust) is a bit more complicated... on gen1 cars you won't have a button if you have sport chrono. You will have a button if you don't have sport chrono. On gen2 cars, you'll always have a button.

 

Thanks, question answered.
