I can't understand why its cheaper to have possibly 5 occupants in a car/van same vehicle than only having 2 occupants in the same vehicle , but classed as a van. That what i don't get. The black box doesn't really concern me as it will make sure he's a good lad, but i was just showing the difference. For the girls cars it was only £300 more expensive so I paid the extra, for me really so I didn't bugger up there insurance when I drove it.
