Makes me chuckle..... Big huge title claiming they are 100% road legal, then tiny font at the bottom of the advert: 'Sold as show/display use only'
That's how they sell them without taking your V5 and ID details.
The plates themselves meet UK requirements.
They'll be the same plates you end up with by going to their website, ordering, then sending your original V5 (not a copy) and a utility bill or ID. I preferred the quicker option that didn't require my docs to be sent off!
