Top 10 most reliable family cars By studying data from about 30,000 of its policies linked to small family, family and MPV-style cars, Warranty Direct claims to have found the 10 most reliable family cars - just in time to start planning the annual summer holiday. The study analysed cars aged three to five years, and found the 10 models that suffered the fewest breakdowns. It also examined what the most common failure for each was and how much the largest claim cost. Duncan McClure Fisher, managing director of Warranty Direct, said: "Most cars will go wrong at some stage but there's nothing worse than the family's excitement at setting off on holiday being destroyed by a morning spent on the hard shoulder. And, as well as the inconvenience to your holiday, a breakdown can also put a serious dent in your wallet.
