Clutch life totally depends on driving habits and driving conditions. Oil leaks or random mechanical failure of the clutch components can result in a shortened clutch life, but I would expect to get 100,000 miles from a clutch under "normal" driving conditions.
Extremely appreciated, for your reply.... I purchase 17 months ago, a 2001 boxter with just 36K miles / 1 owner . . .a ''ladies''' shopping car (wealthy family) just hit the 43K mark now...it's reassuring to know, that I 'should get' at least 60 - 70K as I don't push the car to extremes. - -Thank you Autotachpat.
