A study by Warranty Direct has revealed what it says are the 10 most reliable used cars of the last 15 years.

The company was founded in 1997 and has examined more than 200,000 customer policies between then and now to determine this list.

The cars were judged using Warranty Direct's Reliability Index, which rates reliability by looking at a number of factors including how often the car breaks down, the cost of repair, mileage and age.

This is used to calculate a Reliability Index rating; the lower the score, the more reliable the car.
