I wore the clutch out on the first manual I had in just over 6 years (too much slipping out slowly, I'm sure). After that, it went another 15 years or so before other reasons made the clutch/tranny life moot. Replacing a clutch is quite a bit cheaper, though, than rebuilding an entire automatic tranny.
