i THINK if you have the "E" mark on the left hand side is more illegal than anything, i remember my mate got done in his polo for having them, but the copper said its mainly because he had the German symbol at the side..

could be pish, but if you were to get them, you should get the GB bit at the side.
 
got mine from dubmesiter. had no probs wilth police yet touch wood and been on for about two months.
 
Why are these not road legal? even with GB on them.

Mainly because it uses a different font, and also the plates aren't always reflective. Plus I also think its because you can get these plates done without any identification / proof of ownership. Whereas when you go to get a proper numberplate made up you need with you your documents (well I think you do anyway).

What people recommend is you change the front plate, but leave the rear plate standard, as Police only really check the plate when they are driving behind you.

yeh they do, jst not on the configurator bit. when you come to place the order, you get given the option i think
