.jpg?width=620)
Every year, thousands of car owners take part in the Honest John Satisfaction Index, which seeks to identify the best and most reliable cars in the UK. Of course, it also names the cars you should avoid.
As well as looking at things like fuel economy, practicality and safety, owners are asked to rate their cars out of ten for reliability. This makes the annual survey a hugely invaluable resource, because the results are based on the feedback from actual owners who are living with the cars on a daily basis. On school runs, daily commutes and shopping trips.
There are no guarantees of reliability, but by choosing one of the following cars, you stand a better chance of owning a car that's likely to give you the fewest sleepless nights.

Jaguar F-Pace
Reliable car score: 9.87
Another Jaguar making the top ten, with the Jaguar F-Pace recording an impressive average of 9.87 for reliability according to its owners. It also achieved strong scores for performance and interior quality, but a low score of 8.30 for repair costs suggests problems, although rare, can be expensive to fix. Still, this is an impressive result for Jaguar, not a brand that's usually associated with reliable cars.
