Reliability Survey 2012
Choosing the most reliable used car is a priority for many buyers and our 2012 Reliability Survey can help you. Using real-world data from warranty provider Warranty Direct, this is the definitive list of the most - and least reliable - cars you can buy.

As well as listing the most reliable cars by brand, we've also listed of the top 10 most reliable cars - and the worst of all - . Whether you're after a supermini, SUV or executive saloon, our guide will tell you which models will let you down, and which won't.

How is the survey carried out?
Not every make and model of car is included in our survey – only the cars that Warranty Direct has policies for, and only if there are more than 50 vehicles covered. This large sample size means that we get a more accurate assessment of what really fails. We remove vehicles that are more than eight years old from the results; with vehicles over that age, reliability is more about how well the car has been cared for than its basic design.

What is the Reliability Index?
This is Warranty Direct’s quick and easy way to compare cars by taking all the key aspects of reliability into account. It factors in the number of times a car breaks down, as well as the average repair cost and repair time. The lower the number, the better the car. As a guide, an average Reliability Index score is around 100.

How are the results shown?
We’ve listed the manufacturers from the best to the worst, according to how often their cars break down. We’ve also listed the top 10 and the worst of all – sorted by their Reliability Index. This gives a better comparison when considering the overall reliability of a car against its peers.
