Which? has launched its 2014 car reliability survey, and those who participate are in with the chance of winning £2500 – the equivalent of a year’s free fuel for an average family car.

Last year 47,572 people responded to the Which? Car Survey, which found that the highest average repair costs were for the Land Rover Discovery 3, and that the Renault Megane Sport Tourer (2003-2009) had the lowest customer satisfaction rating.

The survey is used to compile lists of the least and most reliable cars in each class, and also gives an average annual repair costs, giving car buyers and owners and idea of what sort of garage bills they can expect depending on how old their cars are.

The survey takes around 15 minutes to complete and those who participate will be automatically entered into the prize draw to win £2500.
