I took my 98.5 Mystique LS/auto for a oil/coolant/transmission fluid change today. I have 59,000 miles on the car.

The service advisor at the neighborhood service center noticed that the serpentine belt had cuts and advised me to replace them.

He quoted me a price on the belt at $57.78 and labor at 0.7 hours for $45.49. The labor fee sounded reasonable, but the price on the belt seemed high- based on web pricing searches.

As for the water pump, I'm getting worried about failing and wanted to replace it. Again, he quoted a price of $99.90 (I asked if the pump had metal impellars) and labor for 1.5 hours at $97.48

Any suggestions? Should I buy the parts and have them install it? Or should I just shut up and go with their estimates?
