Funny this topic coming up today, I just bought a plate off Ebay a couple of weeks ago. T3 RDW I couldn't believe I got it for £51 inc all fees being already paid. Anyway the seller was a bit stroppy but I got the document in the end.
I fitted it to my car today.
It doesnt mean anything to me it just takes the age away from my car.
I noticed a 1 letter 1 number went last week on Ebay for £122.
