Phone and web broker Quotelinedirect* has an exclusive deal with Europ Assistance for a £59 annual ‘AutoService’ policy covering any individual vehicle (less than 20 years old) for a year.
This includes home-start, and onward travel for passengers plus up to 90 days a year cover in Europe. However, those not going to Europe regularly should stick with a UK-only policy and take out separate cover if needed for a single trip.
