The UK’s most expensive number plate to date is the F1 registration number purchased by a British businessman for £440,625 in 2008, though that’s just small change compared to the £7m spent by Abu Dhabi-based Saeed Khouri on the 1 number plate – officially the largest sum of money ever spent on a registration number.

It should be noted that there are no restrictions on using a vanity or cherished registration on a car that is newer than the original date of the registration plate, but it is prohibited to transfer a registration that is newer than the vehicle it is used on. This is to prevent the transfer of newer registrations to older vehicles as a measure to protect consumers.

It had been expected to sell for between £15,000 and £25,000 but the first Manx vehicle registration plate ever to be issued was eventually sold last week for £100,000. It is, says auctioneer Murray Keefe, a valuable piece of Manx history.

“It was the first Isle of Man number plate and people do like to have number 1. At the auction we had 4 telephone lines wanting to bid on the number plate and quite a few bidding in the room so I was not surprised it made so much money knowing that some of the plates in the United Kingdom make substantially more than that.
