You don't find many black MK1 dashes coz they never came in black. Mine was brown but faded and I couldn't find matt brown paint.
I agree it's good to be different / unique but not to the point where things look disgusting and people make odd comments or possibly call you a chav.
At the end of the day it's you car dude so it's down to your taste and preference.
Have you thought about things like flocking? Maybe a Black flock with white detailing or grey detailng?
