Can anyone explain why my little Seat Inca van (1.9D) costs €3.10 to go through the Westlink while my friends 2.5L Diesel costs €1.80!?! It is solely because mine is a commercial vehicle. Thus, does this mean that I am being charged extra as I am going to use my van for something useful like work rather than dropping kids off to school in an unnecessarily large jeep! I actually nip through the car section times anyway, lash the money in the basket and away with me. Hoping not to receive a fine in the post!! Anyone know what the story is with this as a matter of interest?
