Looking for a reliable car that won't let you down? Whether you're after a new or used car, our unique survey reveals the most reliable cars in the UK.

Thanks to our research, we can tell you which are the most reliable cars. So whether you're looking for a reliable small car, a sports car or a reliable SUV, you can use our research to find a car you can trust - and avoid the ones you can't.

A car could go 100 miles on a gallon of fuel, handle like a dream and be comfier than your favourite armchair, but it counts for nought if its beset with faults, breakdowns and pricey repairs.

In our annual Which? Car Survey, we ask thousands of motorists about their cars, what issues they've had and how expensive any repairs have been. With the data we collect we determine how reliable a model of car is in its first three years and in years three to eight of its life.

If we find a car too unreliable, then it can't be a Best Buy car, regardless of how well it performed in our tests.

As a Which? member you get exclusive access to our most reliable car brands tool, below. If you already know what car you want, head straight to our car reviews.

Revealed: the most reliable cars

We've surveyed more than 43,000 car owners so we can provide robust reliability ratings for hundreds of cars. You can use our research to make sure you don't throw away your money on a car that will let you down.

You can't go by a car's sales figures to determine if it's going to be reliable. We've discovered that a shocking one in five owners of one of the UK's best-selling cars experienced a breakdown in the past year.
