Renault named best for repair costs

That’s because according to an industry-wide annual reliability survey, average repair bills on Renault cars are cheaper than any other manufacturer.

The average repair bill for a Renault car was £226, the cheapest in the industry. In contrast, the most expensive, with a massive average repair bill of £717, was supercar manufacturer Porsche.

The survey, by What Car? and insurance company Warranty Direct, studied 32 manufacturers, and found French marque Renault finished just ahead of Fiat (£227) to finish top of the list.

Ford, Citroen, Vauxhall, Peugeot and Seat all finished in the top ten least expensive with average repairs under £290. The most expensive list was dominated by luxury manufacturers such as Porsche, Audi and Lexus.

The survey also discovered the most reliable car brands based on frequency of failure, length of time spent in the workshop, average repair cost, age and mileage.

The winner was Honda, and Japanese manufacturers continued to dominate the top ten, with Mazda and Kia both scoring highly.

What Car? editor, Steve Fowler, said: "This year’s survey produced some interesting results. Several prestige manufacturers have suffered embarrassing failure rates, while brands that buyers may not associate with reliability have shown a marked improvement."

The survey looked at cars aged between three and ten years old, and manufacturers such as Kia are expected to score well in future surveys as more models are brought out. For example, the EuroNCAP five-star-rated Kia Soul will not have been included in the 2010 survey.

Warranty Direct managing director, Duncan McClure Fisher, said: "Car manufacturers are constantly making great strides in building more reliable vehicles, so this survey is not a reflection on new cars coming out now – we won’t see hard data on those vehicles for three or four years."
