Will adding a storage box, or putting bicycles on the rear of my car change the price I pay?

Anything extra on the top or rear of your car will change the dimensions and what space your vehicle takes up, therefore, this could change where you are allocated and the price you pay. If you decide after booking to add any kind of accessory, you must let us know prior to travel as we may not be able to allocate you a suitable space in the same time slot.
