I think we can say it has little regulation !
Wife bought me a plate for our Coupe, lets say £1000.
This year they approached us and said someone was keen to buy a plate with the 3 letters ours has. Offer to buy it from us for £500, maybe £550.
All the others of this format on their page are uniformly above £1000.
We have a spare private plate we had on an old golf so we asked them if they wanted to sell this for us. They send the paperwork which means you have to only offer it through them, cannot sell it directly, owe them a cut etc etc. They don't buy it, no money changes hands. Not heard from them since.
We got our other plate directly from DVLA website. It is very good at helping you find old and new if you play with words.
