Diminished Value Claims: Recovering Your Car's Lost Resale Value

The body shop did good work and the paint matches perfectly. Then you go to trade the car in, the dealer pulls a vehicle history report, sees the crash, and knocks a couple thousand off the offer. That drop in value is called diminished value. Often the at-fault driver's insurer can be made to pay for it. Don't wait for them to offer, though. They rarely mention it.

What is diminished value?

Diminished value (sometimes shortened to "DV") is the difference between what your car was worth right before the crash and what it's worth after repairs. The Maryland Insurance Administration describes it as the loss in value a vehicle can suffer after an accident, even when repairs meet industry standards, simply because the car now has an accident history.

People often talk about three types:

Type	What it means
Inherent diminished value	The car is fully and properly repaired but is still worth less because of its crash history. This is the most common type of claim.
Repair-related diminished value	The car is worth less because the repairs were poor or incomplete. This may be a dispute with the repair shop or insurer about the quality of work.
Immediate diminished value	The drop in value right after the crash, before repairs. Mostly used in appraisal discussions.

When can you claim diminished value?

Against the at-fault driver's insurer (third-party claim)

Most DV claims go this way. If another driver caused the crash, their liability coverage is meant to put you back where you were before. In many states, that includes the lost value of your car, not just the repair bill.

The Maryland guide notes that you generally can't claim diminished value from the other insurer if you were found at fault or contributed to the accident. Fault rules matter here, especially in contributory negligence states like Maryland. See comparative fault explained.

Under your own policy (first-party claim)

Claims under your own collision coverage are harder. Many policies say the insurer will pay to repair or replace your car, not to make up for lost market value, and some policies expressly exclude diminished value. In Maryland, the Insurance Administration's position since 2024 is that uninsured motorist property damage coverage must include diminished value; in other states it depends on the policy. Read your policy or ask your insurer in writing.

When the car is totaled

If the car was declared a total loss, you're generally paid its pre-crash value, so diminished value usually doesn't apply. The Maryland guide adds that a diminished value claim is possible when repair costs plus diminished value don't exceed the car's value just before the accident. See property damage and total loss claims.

What affects how much value is lost?

According to the Maryland Insurance Administration, factors include:

• Make, model, and year
• Mileage
• Condition before the crash
• Prior accident history
• The type of damage (structural, mechanical, or cosmetic)
• How severe the impact was

A two-year-old SUV with 18,000 miles and frame repair will usually take a bigger hit than a 12-year-old sedan that needed a new bumper cover. Buyers care far more about structural work than cosmetic work, and on an older, high-mileage car there may be little value left to lose.

How is it calculated?

There is no single official formula. The Maryland guide states that Maryland law doesn't require any specific method of calculating diminished value. Insurers may use their own internal formulas, which may produce low numbers. Other approaches include:

• Independent appraisal. A licensed or certified appraiser compares your car's pre-crash value with its post-repair value in the local market. This usually costs money, but it gives you a written report.
• Dealer quotes. Ask one or more dealers what they'd offer for your car now, and what they'd have offered for the same car without a crash history.
• Market comparisons. Compare listing prices of similar cars with and without accident histories.

How to make a diminished value claim

1. Confirm the other driver was at fault and that you're claiming against their insurer.
2. Get the repairs completed and keep the final repair invoice, including any supplements showing structural or frame work.
3. Get the vehicle history. See whether the crash appears on a history report.
4. Document the value loss. Get an independent appraisal, dealer statements, or comparable listings.
5. Send a written demand. Include the claim number, a short explanation, your evidence, and a specific amount.
6. Keep notes. The NAIC recommends logging every conversation with an adjuster, including dates and names, and asking for a written explanation of any decision.
7. Negotiate. Expect a counteroffer. Respond with evidence, not just a higher number.

The Maryland guide points out that the at-fault driver's insurer isn't required to tell you that you may have a diminished value claim. You have to raise it.

Sample timeline

When	Step
Right after the crash	Photograph damage; open claim with at-fault insurer
During repairs	Keep the estimate, supplements, and final invoice
After repairs	Get appraisal or dealer quotes
Within a few weeks	Send a written diminished value demand
If denied or lowballed	Ask for written reasons; consider your state insurance department or small claims

Common insurer arguments and how to respond

What the adjuster may say	How you might respond
"Your car was fully repaired, so there's no loss."	Inherent diminished value exists even after proper repairs; provide an appraisal or dealer quotes.
"Our formula shows only a small amount."	Ask for the formula in writing and compare it to real market evidence.
"Your car is too old or has too many miles."	This may be fair for some cars; check whether local market data actually supports it.
"You were partly at fault."	Ask what evidence supports that and how your state's fault rule applies.

If the insurer says no

• Ask why, in writing. Is it a fault issue, a policy exclusion, or a disagreement about the amount?
• Contact your state insurance department. The NAIC suggests consumer services staff can help with disputes about how a claim is handled.
• Consider small claims court. You can often sue the at-fault driver directly for the diminished value if it falls within your state's small claims limit. See small claims court for car accidents.
• Talk to a licensed attorney if the amount is large. The Maryland guide suggests consulting an attorney if you can't reach an agreement.

Don't miss the deadline

A diminished value claim is a property damage claim, which may have a different statute of limitations than an injury claim. In Virginia, for example, actions for injury to property generally must be brought within five years (§ 8.01-243(B)). Other states differ. Check your state on our state law pages.

Before you accept the repair check

• Diminished value is the resale value a car loses after a crash, even with proper repairs.
• Most claims go against the at-fault driver's insurer. Your own policy's language often limits a first-party claim.
• Depending on state law, your share of fault can reduce or bar the claim.
• No formula is universal. An independent appraisal or dealer quotes make the strongest case.
• The insurer may never mention DV, so raise it yourself, in writing.
• At an impasse, your options are the state insurance department, small claims court, or a licensed attorney.
