Those people with 150K on their clutches are going to need a new flywheel when they do change them..
The clutches in these cars can function fine and be chewing the flywheel all to hell for a few thousand miles.

Needing a preventive for a clutch change and running the car into the ground without preventive measures are two different things. If you run the car until it requires a clutch it will require more money to be spent.
