It's not the car, it's the clutch. Superformace cars are or should be all hydraulic. Hyd master and hyd slave or hyd throw-out. I've never seen or heard of anything other than a hydraulic system installed in one.

There are a variety of clutch/pressure plate options depending on preferences and required torque ratings. Driving type & style will make some difference in the unit selected. There will be great differences in pedal pressure depending on the unit.

It could also be that the hydraulic system has degraded. Changing the master cylinder is a PITA as it's behind the brake system but doable. The slave cylinder is easy from under the car. Bleeding the system isn't particularly difficult and will gravity bleed.

You can change a Superformance clutch & trans through the trans tunnel & interior, no need to pull the motor. You'll have to break the tunnel sealant and carpet loose, this isn't usually fun.

Superformance cars will generally hold their value better as indicated in earlier responses.
