Total loss & valuation

My car was repaired but it's worth less now — what is a diminished value claim?

Why the loss is real

Vehicle-history reports mean buyers and dealers see the accident. A repaired car sells for less — and trades in for less — than an identical car with a clean history. That difference is diminished value. It hits hardest on newer, higher-value cars where the history report moves the price most.

Two kinds you'll hear about

• Third-party diminished value — claimed against the at-fault driver's insurer. This is the standard path in most states.
• First-party diminished value — claimed against your own policy. Many states don't allow this; a few do. Check your state.

How these claims are typically documented

1. Keep the repair records — invoices, photos before and after, and the final work order showing quality repairs.
2. Get before-and-after market evidence. Comparable listings for your car with and without an accident history, or dealer quotes showing the trade-in hit.
3. Consider an independent diminished-value appraisal if the amount is worth it — a written appraisal from someone who does these is the standard evidence.
4. Present it in writing to the at-fault insurer with a specific demand number and the documentation behind it.
5. Expect pushback and low formulas. Some insurers use quick formulas that understate the loss. Compare any offer against your own evidence, not their calculator.
