Mines done 95k, had service and MOT last week...the chap at the garage commented how well it drove and how good and clean everything on it was for the miles, wouldn't have believed it's approaching the 100k mark!
Guess it all boils down to how it's been looked after for it's life, but age comes into as well, things start to wear/corrode/perish over the years...especially rubber parts, the miles have no bearing over that.
