Evidently the dear old DVLA have noticed the mistake they made in 2015 when they inadvertently allowed any 25year old vehicle go to a black and white number plate when the original historic cut off date for them was 1st Jan 1973 (I remember it well) when the yellow jobs came in. Anyway they have now moved the goal posts to 1st Jan 1980 which is apropos bugger all. so if there are any with owners with a post 1979 egli or a rebuild on black and white numbers the full force of the law will come down on you from 1st January as the police have nothing else on at the moment.
