There are different options for breakdown cover and which one is cheaper depends on the level of cover required.
Breakdown cover through insurance
AA
RAC
Breakdown cover through manufacturer / dealership
The AA has special relationships with some car manufactures including Toyata, Lexus, Audi, Porsche, VW, Skoda and Suzuki. The price is often cheaper than going direct to the AA and these policies offer European breakdown cover as standard. This is a separate policy with an additional cost if you a direct customer. If you require coverage as a driver or passenger in any vehicle you will need to go direct or use a different provider. Currently there is no separate website for Guernsey. Call 03447016210.
