944 died

well this morning as I went to leave to go snowboarding, I got into the 944 and the clutch was depressed to the floor. Not a good sign. there was also a large puddle under the car. I am hoping that I will not need to replace the entire clutch. I think it may be the master cylinder(since there were no signs of the clutch failing before), but have no idea what kind of cost or work is involved in fixing it. The porsche place I like is in San Rafael, and the car in in Orangevale. (about 150 miles away).
