Some info just seen on another website :
Personally I have been running black and silver number plates on my 1980 SC for a while now, never had any issues.
Will actually continue to do so as the text says ''To prevent any vehicle constructed after 1st January 1980 from the ability to display the black and silver number plates". My car was first registered in 1980 but actually built (therefore constructed) in 1979 as per the Porsche Certificate issued with the car so I should still be fine ??
Another one of these stupid rules IMHO but hey, these guys obviously need to justify their power !!!!
