My wife has a Toyota Aygo that's coming to end of its three-year manufacturer warranty. The car does about 8000 miles per year, mainly on running local errands and commuting. We have option of buying extended warranty from various places - but the best deal is with a local-ish Toyota main dealer, who's offering three-years' extension for about £480.

Just wondering whether this is worthwhile, or should I take the risk and pay for stuff as it happens?
