Got a 3 yr lease on a 911 Carrera S and wondering how many miles will the clutch last. I am on my second year, all city driving and drive like Granny, no racing. If any one has the experience, would appreciate some insight.

 

You did not say which year 911S. Older and vintage models can be different.

I've seen recent models driven by people who are gentle on the clutch (as opposed to gentle on the car) go 75K plus (and maybe much more than that -- I just have no firsthand knowledge of a clutch lasting longer but it had not failed at that point -- she just sold the car and I didn't know the other driver or ever talk to them again).
On the other hand I've seen folks I don't consider bad drivers wear one out in less than 40K miles.
