I'm pretty sure the "II COB" is simply the car's license plate / vehicle registration number. I've never been to the U.K., but I think it works differently from here in North America; that is, the vehicle registration / license plate is tied to the car, not the owner, and is passed on when the owner sells it to another person. But Trevor would know better than me how it works in Ol' Blighty.
