So-called ‘dateless’ registrations like 'SUO 423' can be assigned to any vehicle regardless of age and are therefore exceedingly desirable. They serve as a reminder of a bygone age, when there were far fewer cars on our roads, so whether it’s to go on your vintage vehicle, or simply adorn a favourite car with a distinctive registration, ‘SUO 423’ would be a great number plate. Better still, if ‘SUO’ spells out your initials, and you live at number 423, it really couldn’t be more apt.
