How We Rank These Cars

The iSeeCars brand reliability ratings indicate how dependable and long-lasting each car brand is based on the durability of its models

The best brands offer models with the highest reliability ratings within their respective vehicle segments. For example, Toyota is perhaps the best brand for reliability, as a number of its models are ranked number one in their categories. Along with the rankings and Reliability scores, we show comprehensive iSeeCars ratings for each brand’s models, because we believe multiple factors should be taken into account when buyers are seeking the best overall vehicle. Two of these factors are safety and resale value, both of which are included in our ratings system.

The overall iSeeCars Score is an analysis of these three factors: reliability, resale value and safety. It is calculated based on the latest research and analysis by our data science team. The data analysis comes from over 12 million new and used vehicles in our Longest-Lasting Cars and 5-Year Depreciation Studies, combined with NHTSA and IIHS Safety Ratings.

Vehicles are scored in three categories:

Reliability

The reliability score represents an analysis of iSeeCars' proprietary research on the longest-lasting vehicles.

Value Retention

The value retention score is based on our data science team's statistical analysis and prediction of 5-year depreciation from MSRP to determine which cars hold their value best, using US Bureau of Labor Statistics data to adjust for inflation.

Safety

The safety score is calculated based on the last five years of crash test ratings from the National Highway Traffic Safety Administration (NHTSA) and incorporates the latest Top Safety Pick information from the Insurance Institute for Highway Safety (IIHS).
