How many miles did the stock clutch last?

In my 1995 coupe, 2,000 RPM in 6th gear equals 80 MPH. Actually I get better acceleration in 6th with just a bit of throttle, going wide open does not give more acceleration in that scenario.
I'm sure you are right. First gear *feels* super short... I can very nearly dump the clutch in 1st and it will not stall.
How exactly do we check the color of the fluid in the slave cylinder? It's made of metal.
While it's fairly hard to get to - you might want to take a quick peek at the color of the fluid in the clutch slave cylinder. It's brake fluid - so it should be relatively clear - If it's black - it tells you the owner does not go completely nuts with fluid changing, and that if you buy the car - a clutch fluid change should be on your spring / summer "to do" list.

Yeah my new fluid looks darker in only 8 months and I only drive it 2-3 days per week at most.
Last time I refreshed the master fluid, I forgot to wipe the sediment from the bottom of the cylinder and it got dirty right away. Oops

You should change it when it gets darker. Dark brake fluid means 2 things... dirt and possible moisture in the fluid. Its a 10 minute job with a turkey baster and will improve pedal feel, master & slave life and clutch life overall.... no brainier really

The clutch fluid in these cars gets dirty really quickly. I believe it’s a combination of the rubber liner in the SS hose deteriorating and seal wear, unlike brakes the clutch cylinder seals see a full stroke on each use. Good luck keeping it clean. Turkey baster swaps the fluid in the res, does nothing for the fluid in the line and cylinders.
I vacuum bleed roughly every other year.

In all seriousness, I can't quite do that with my lopey idle and 13lb flywheel, but even my engine is pretty hard to stall out.
