I've got a car for sale and an interested party has asked for the reg no. & ref no. from the registration document (V5) for a car history check, seems fair enough but is the registration document reference no. necessary? The number plate registration is actually clear in the pics, just wondering if in this day and age having possession of someone's V5 reference no. allows some sort of scam or other..
Maybe paraniod but don't want to be suckered into anything
