1GR - what an exciting lunch break you have had today Rob! As you said, it must have cost a bit. A few years ago my cousin bought me a book with car number plates in it and there were dozens of pictures of the famous and not so famous with their cars.
My Aunt lives immediately opposite Bernard Manning (big comedian, who swears a lot) on the outskirts of Manchester, and he has a huge American car with BJM 1 and local kids are always chalking the J to look like a U (BUM 1).
I will have to check if there is an updated version of the book to see if there are any Clios in it!!
