What you can do with it

Here’s what you can do with the report.

The report gives you something specific to bring to the insurer. It shows how the estimate was built, but it does not guarantee payment or replace legal advice.

01

Ask the insurer to reconsider

Share the report with the claim handler and ask them to review the diminished-value amount against the documented evidence.

02

Compare the insurer’s offer

Put the offer beside the report’s estimate, source-linked comparables, and adjustment notes so the differences are clear.

03

Keep your claim record organized

Save the report with your final repair invoice, photos, letters, and emails so the basis for your request is easy to follow.

STEP 01 / QUICK CHECK

Seven short questions.

We offer checkout when every answer matches Donut’s current California eligibility requirements. Unsure answers receive additional review first.

Did the accident and claim happen in California?

Donut currently serves accidents and claims in California.

Are the repairs finished?

A final repair invoice is best.

Has the other driver’s insurer accepted responsibility?

This service is for third-party claims with accepted liability.

Was the vehicle declared a total loss?

Total-loss claims follow a different valuation path.

Have you signed a property-damage or final release?

If you are unsure, we should check it before you pay.

Is this your vehicle with no prior damage or branded title?

Prior collisions, unresolved damage, salvage, rebuilt, or flood titles need a different review.

Was the car used only for personal driving?

Choose no or unsure for rideshare, business, or government use. Unusual claim situations receive additional review.
