Background on Car Write-Off Categories

When a car faces significant damage, it’s not always the end of its journey. Insurance companies evaluate the extent of the damage and classify the vehicle into specific categories. These categories help determine whether the car should be repaired, sold, or scrapped. Here’s a brief overview:

  • Cat A: Cars that are so severely damaged that they can never return to the road. Every part of these vehicles must be crushed.
  • Cat B: While these cars can’t return to the roads either, some of their parts might be salvaged and reused.
  • Cat S (formerly Cat C): Cars that have suffered structural damage. Though repairable, the cost might exceed the vehicle’s value.
  • Cat N (formerly Cat D): This is where our primary focus lies. These cars have not suffered structural damage but might have other issues that could be cosmetic or related to safety.

Understanding these categories is crucial, especially if you’re in the market for a used car. It ensures you’re aware of the vehicle’s history and any potential issues it might have.

  • Classification: A car is labeled as Cat N when the insurance company believes the repair costs (non-structural) might exceed the vehicle’s value, even if the car is perfectly drivable after repairs.
