Failed Clutch Master Cylinder

1991Z32

OP here. Was away for Thanksgiving and thanks for the input.

The symptoms was not a sudden failure of the clutch but a gradual lowering of the engagement point (engaging quicker) and I had to push completely to the floor to disengage at the end. There was never any issue with the pedal returning to the top of its position. The car is a 2010 with 18k miles.

Here is the situation - the dealer said it was the CMC and the CSC. Quoting me $1100. The parts should be arriving Wednesday 12/1.
Frankly, I am not used to dealing with dealers because I have never had a major component go on a car with this few miles. Either the car was way beyond warranty or it was completely covered.
My friend used to work at this dealer and told me they would shoot me straight. Hopefully he's right, but who really knows.

Where things are right now, I can't really judge the dealer's assessment to what actually failed, as there could've been adverse effects with the car being used very sparingly in the past 6 years — so it could be both CSC and CMC. Age could've just eaten at the seals or whatever. Regardless of what failed, both would have to be replaced at the same time.

Like said already, if it's an OEM CSC, that's a real waste. If you have a competent specialist shop in town, you'd be paying that much or less to have an aftermarket CSC + new OEM CMC.

Like not to it shove in your face, but this is the very first thing that has to be taken care of with the the manual version of the car. It's such a (or rather, "the") prominent issue that anyone should be aware of if they did research on this car before buying, especially if it's a used car...yet it seems a fair share of people are too fixated on engine mods, etc, and just put off something that could spontaneously fail. Even if it's progressive, the time frame between early symptoms and failure could be as short as the limp home. You just never know.

Some people literally say "I'll just wait until it goes" — as in, wait until they're possibly stranded on the road, have to call a towing service that might fudge up the underside of the car while towing, then order the parts, and then arrange the work to be done, which my possibly require another tow, maybe even sort out a rental in the meantime. All that downtime and likely additional cost vs. just getting the parts and job done on a scheduled day.

That kinda does translate to "expect to fork over another grand or so soon after buying the car", which sucks, but 7 years and Nissan kept the car this way.
