Firstly having number plates like that is NOT an endorsable offence
If you are unlucky you could get a £30 fine
(Obviously depends on the Police Officer)
I have just paid a £30 fine for my Son who had Euro plates on his car.
Simliar to this. He did not get any points.
You might want to get hold of some of these surrounds from Halfrauds
Surrounds
But obviuosly not in pink
Unless it tickles your fancy
They do them in a few different colours
You don't need to drill holes in your plates as they literally slide in and out.
Might want to put a bit of double sided on the plates to secure them in the surrounds for piece of mind.
Very easy to swap the plates around if needed
