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.

Even in the early days, people recognised the significance and enjoyment brought by owning a prestigious or personalised number plate and often kept them within the family for many years. Their significance is often highly personalised to their owners. Some like to have a registration that originated in their local area, some are attracted to owning their own initials and others enjoy the fun of a word based registration mark.

Since the dvla introduced the bsau145d legislation it has been increasingly difficult for motorists to obtain number plates with anything other than legal spacing.

There is however another line of argument for the defence of the serial mis spacer. They say that a number plate that has been altered to make a word or a name is much more memorable in the event of an incident.
They also argue that the dvla blatantly auction registration numbers that would be virtually worthless without mis spacing.
