Am i allowed to have a black rear numberplate on my car?? I saw a black MC (white lights and roof with aero kit) just like mine with a black numberplate and it looked soooo much better than the yellow ones people have. I dont want to get in trouble if its illegal though. The car im refering to is featured in the first issue of this new mini magazine, called New Mini on page 6. Does anybody know why cars have one white and one yellow numberplate?
