No doubt if it is the original it could go anytime, as I say I bought mine on 68k and the clutch started to get really stiff within 6 months, but a good sign that the car has been driven well in my book
48k is nothing for a clutch in a well looked after Zed mine was ok to over 70k i would say it is the sign of a well looked after car, not everyone heel & toes it everywhere
I would say black, polished seems to be done to death
But then I am not a blingy person, I am just quiet and shy and like to just blend into the background...
Have a chat with Daryl what he doesn't know about CF is not worth knowing
Alternatively RT Performance?
I find that black Tcut paste is very good for covering minor cracks or spidering....
