I've got exactly the plate I wanted - but I wouldn't want to put it on here
It wasn't one that was available to buy from DVLA but I was able to track down the owner of the car which had the reg (which meant nothing to him), I bought him a personal plate and he transferred his to me, everybody happy
I like plates that make up words rather than just initials, like Scen1cs example. Especially when they are relatively cheap but look really good - Selwonk's is a cracker for him.
It's very much personal taste though - some people love 'em, some hate them. When the 51's first came out I bought a couple to sell on. My favourite was FA51 CAR which, last time I looked was on an Aston. The plate looked great made up, I wish I'd kept it now but I got good money for it and needed the dosh at the time.
