I agree with citydude. saves the transmission and clutch. Never worn out a clutch though but put two sets of clutch master cylinder seals on Isusu Trooper. I think the reason for this was that the car was used mainly on highway 401 north of Toronto. If you use that highway in the rush hour twice a day you will know what I mean. Put too much stress on my left leg also. Automatics after that car. Incidentally, if you have a problem with clutch operation, make sure it is a clutch problem and not just master cylinder seals. The latter are just pennies to replace and you can do it yourself easily if you are a bit handy.
