107k on mine, absolutly no issues at all. Tranny feels as good as a new one, and the clutch is cherry. It's all about the driver, time has nothing to do with it, I agree with that.
I've never had a clutch go bad, 3 stangs and 1 Mclaren Capri, so far, 3 5.0's and my '99 Limited. The way I pull out is alot different than others, I dont just compensate gas when letting out the clutch, I tap the gas...like, tap tap tap, jumping the rpm up a few times as I pull out, i'd like to think i'm putting no wear on it at all. I dunno, i'm sure there's a few of you who understand what I mean.
I put 160k on my Capri 5.0, sold it to a friend, and he's still driving it with no problems at 179k. The motor sounds like new still, and I got it with VERY low miles. Tranny is perfect.
