I'm right at 87k, and it seems to be doing fine. Don't really know how it was driven untill I bought it at 52k, but I do my best not to slip it too much.
My last car was a 94 eclipse 1.8L; it was at about 85k when i bought it, i detected the worn clutch slippage soon after, and put another 15k on it before i replaced the clutch. That year of tiptoeing around that clutch taught me how to preserve a clutch.
I usually pull off in 2nd from anything other than a complete dead stop. Saves a starting slip, and another gear change. First gear is so short in the MTX-75 anyway...
Peace
