* Vehicle make and model: The cost to repair a vehicle and its safety features heavily influence premiums.
* Driver's history: This includes driving record, age, and experience.
* Location: Rates vary based on geographic area due to factors like theft rates and accident frequency.
* Coverage level: Comprehensive and collision coverage are more expensive than liability-only coverage.
While some insurers *might* use subjective criteria in their algorithms, the color of a car is not typically one of them. Any perceived difference in cost is likely due to correlation with other factors, rather than the color itself. For example, certain sporty car models might be more often red, and those models might be more expensive to insure due to higher repair costs and a higher risk profile.
