Mines on about 48k (I think lol, its in the 40s) and the drivers one has been showing signs of wear for sometime now. Its inevetable as your always going to rub it when getting in / out of the car. Passanger ones isnt too bad but again, shows sign of wear.
They are not too bad to the point where Im thinking of getting sorted. I would have thought come 80+ they will looks pretty poor and will need some TLC.
