What is typical clutch wear expectation and does this engine use timing belts?

Thanks Patrick. That was very helpful. I'm so glad I've discovered this excellent site. Repair Pal says a clutch replacement in this area (everything costs more in Hawaii due to shipping across the ocean)is between $821 and $1224. The Kelley blubook for an excellent condition vehicle is $1125. This would mean that if this car has never had a clutch I could be looking at twice the price. Yikes. I seem to remember that a way to test a clutch is to put the parking brake on, put the shifter in 4th gear, step on the gas a little bit and let the clutch out. If the engine dies abruptly the clutch has some meat left on it but if it dies gradually with the rpms going down over a second or two it indicates the clutch is slipping. Does this test concur with your expertise?
