It depends on driving style. I just changed mine a few weeks ago while it was being repaired for a slight dent in the front and it had done 104k.
My friend's only done 62k before he had to change it but he spent a lot of time in the city and driving hard.
Any indication...have a choice to make, sell up or drive until it (may or may not) go on me...have a lot of miles to do this year so need to decide and cost or changing vs cost of fixing anything is the factor
Also, was in multi-storey last night and by the third level, she seemed to be slipping like crazy, felt horrible.....
