About SGM 400
Dateless registrations avoid an obvious vehicle age marker, which can make short combinations more flexible across prestige vehicles and long-term private ownership. The GM index mark traces back to Motherwell and Wishaw, now associated with Scotland. At 6 characters, SGM 400 is a standard-length registration for this era.
