MIne had one at 60K along with a £1450 bill

luckily it was before i bought the car. The cost was due to needing a new flywheel, not sure why, but the receipts make grim reading. ANyway, its nice having a 75k car that has a really tight 'as new' clutch.
Unless something fails or the car is driven by a moron, I see no reason why it shouldn't do 120K+ before wearing out. My Audi S3 had done 135K on the same clutch, still worked but was losing some of its 'bite'
