Which? Car Survey 2015

The Which? Car Survey is the most robust survey of car reliability and satisfaction in the UK; we received feedback on around 58,000 cars in 2015 and believe ours is the most accurate indication of how dependable your next car will be. 

While rival surveys might give you a reliability rating like we do, no other goes into the same detail as Which? – we not only tell you how reliable a car is, we can also give an indication of the average total cost of annual repair costs, as well as how many days a model spends off the road each year on average.

What you tell us about the car you own has a big impact on the scores we give each car model in our reviews, and also has a big say in which are deemed Best Buys - and which are so unreliable that they’re given Don’t Buy recommendations.

As well as costs, we can tell you what is most likely to go wrong with each specific model we cover in the survey - go to our car reviews to find the model you want specific reliability data on.

The faults are rated by how serious they are, to dictate the reliability rating. It also means we can tell you which faults are most likely for all cars.
