How Modifying a Classic Car Changes the Coverage You Might Need 

Customizing classic cars is a popular way to make them truly unique. However, making modifications to enhance their performance, appearance or comfort can significantly affect your insurance needs. Below is a guide to help you understand how changes to your vehicle may impact your coverage, so you can secure the right financial protection.

How Modifications Affect Classic Car Insurance

When you modify your vehicle, standard classic car insurance policies may no longer provide adequate coverage. Since traditional auto policies are often designed for unmodified vehicles, they may not account for the increased value or unique risks associated with custom parts and upgrades. Some common modifications that can impact your insurance include:

  • Engine upgrades or swaps
  • Custom paint jobs or bodywork
  • Suspension or brake enhancements
  • Interior restorations or upgrades
  • Performance modifications

These changes can increase the car’s value, alter its risk profile, or affect its eligibility for certain types of coverage.

Specialty Coverage for Modified Classic Cars

After making changes to your vehicle, you may need to consider specialty auto insurance or add endorsements to your policy to cover custom parts and equipment. Key coverage options may include the following:

  • Agreed value coverage may cover the full appraised value of your modified classic, not just its depreciated market value.
  • Custom parts and equipment coverage may extend to a vehicle’s aftermarket or custom components.
  • Spare parts coverage may help cover the cost of rare or hard-to-find replacement parts.
