Model reliability 0-4 years

How we test model reliability 0-4 years

How reliable this car is, based on the real life feedback of current owners as collected in our annual Which? car survey. We divide all reliability feedback into three age groups: cars aged up to four years, five to nine years, and 10 to 15 years. A car cannot be a Best Buy if: It's available to buy new and has a 0-4-year model reliability score of two stars or less; or it's only available on the used market and has a 5-9-year model reliability score of two stars or less; or it's only available on the used market and launched less than five years ago and has a 0-4-year model reliability score of two stars of less.
