"How long is a piece of string?" BUT;
What would you consider to be an average number of miles on one clutch given that 80% of your mileage is on motorways in 5th and not urban chop and change driving? I have done 70k on a clutch that was changed sometime before I took ownership and was just starting to wonder how much longer I could reasonably expect to get AND what the symptoms of a wearing clutch plate are (apart from the usual slippage under acceleration)?
Thanks,
Greg
