I've got about 85K miles on my 05 QP now, done the clutch twice; once at about 28 and the other time after about 31K. I always drive in Manual/Sport. Lots of highway miles in my mix; probably 60 to 70%.
Got good news today. 32K on the odometer and the original clutch is at 55%! I drive about 100 miles round trip into Washington, DC about three times a week. About a third of the time I'm in non-highway conditions. I always drive in sport mode and always disengage the clutch at stops/traffic lights.
