I'm 5'8'' 165lb and fit great ...actually I find if I don't recline the seat it pushes hard on my lats, as consumers reports said back in 2005 when they reviewed the car, drivers will either find the seats very comfortable or not at all.
I am 6'1 180lbs, mostly legs. I can't fit in a 986 comfortably without the full poser seats. My head will also hit the rollbar in the event of a collision. In a 987 I can't even have the seat all the back. That is why I am looking for a 987.
