my clutch seems to require a large amount of force to depress. The car has 120,000 on the original clutch. It works fine with no slippage, just a lot of force to depress.
I test drove an 88 M6 last year with about 100,000 that seemed to take less effort. My thought was that the M cars had a stiffer clutch. If so, mine seems to have a problem.
