Detailed Answer
When a vehicle is damaged in a crash and repaired, its market value will often drop below what it would have been without the accident. That loss of market value is called diminished value. Proving diminished value in Wyoming requires a tight package of documentation, a credible appraisal using accepted methods, and a clear demand to the insurer. This section explains what to collect, how a diminished-value appraisal works, and the practical steps to present a claim.
What diminished value covers
Diminished value is the difference between the vehicle’s fair market value immediately before the accident and its fair market value after repairs (market value, not repair cost). Insurers handle these claims differently; some will consider them under your policy or as part of a third-party claim. If the other driver was at fault, you typically present diminished-value documentation to that driver’s liability insurer.
Key documentation to collect
- Accident and claim records: police report (if any), claim number, insurer contact information, and the other party’s insurance data.
- Photos: clear, dated before-and-after photos (front, rear, both sides, closeups of repaired areas, VIN plate, odometer).
- Repair records: initial repair estimate(s), final repair invoice(s) with line-item parts and labor, and the name and contact of the repair facility.
- Vehicle history report: Carfax or AutoCheck showing the accident and repairs. This helps prove the post-repair history that reduces value.
- Evidence of pre‑accident condition and value: receipts for recent maintenance or upgrades, photos of the vehicle before the crash (if available), and pre-accident market data (Kelley Blue Book, NADA Guides, Edmunds or similar).
- Comparable sales (comps): listings or recent sales of similar year/make/model/trim/mileage vehicles in your local market, both with and without accident history.
- Independent appraisal(s): a written diminished-value appraisal or report from a qualified vehicle appraiser. See the appraisal process below.
- Repair quality evidence: warranties from the repair shop, parts brand documentation, and any statements about frame or structural work.
How a diminished-value appraisal works
There are three common appraisal approaches. Credible appraisals usually prioritize the market (sales-comparison) approach:
- Market (sales-comparison) approach: The appraiser gathers recent, local sales of comparable vehicles (age, trim, mileage, options) and adjusts for condition and accident history. The appraiser estimates the vehicle’s fair market value before the accident and what similar repaired vehicles sell for after an accident is recorded. The difference is the diminished value.
- Cost-to-cure approach: Estimates how much a buyer would discount price because additional work or perceived defects remain after repairs. This method is less persuasive unless there are visible unresolved defects.
- Income or residual methods: Rarely used for standard passenger cars; more common in specialty or commercial vehicles.
The appraiser should:
- Conduct a physical inspection and take dated photos of the vehicle.
- Document sources for pre- and post-accident values (KBB, NADA, local sales).
- Include a detailed explanation of the methodology and calculations used to reach the diminished-value number.
- Provide credentials (e.g., automotive appraiser certification, ASE credentials, or credentials from a recognized appraisal organization) and a signed, dated report.
Preparing your demand to the insurer
- Assemble a demand package: cover letter, the appraisal report, photos, repair invoices, vehicle history report, comps, and a settlement demand number with a reasonable deadline (typically 14–30 days).
- Send the package via certified mail and keep delivery records. Also email it to the claims adjuster if you have their address.
- If the insurer responds with a low offer or denies the claim, request a written explanation and cite the appraisal and market comparables in your reply.
If the insurer won’t pay
If negotiations stall, options include filing a complaint with the Wyoming Department of Insurance, pursuing the matter in small claims court, or consulting a lawyer for an attorney demand letter or lawsuit. The Wyoming Department of Insurance can explain complaint procedures and consumer protections; you can find resources at the Wyoming Department of Insurance website: https://doi.wyo.gov.

Tips on choosing an appraiser
- Look for an appraiser who provides a clear, written diminished-value report with market comparables and a step-by-step calculation.
- Ask whether the appraiser follows the Uniform Standards of Professional Appraisal Practice (USPAP) or other recognized standards: https://appraisalfoundation.org/uspap/.
- Avoid “formulas” with no market backup. A reliable appraisal ties its opinion to real local sales data.
Practical considerations in Wyoming
Wyoming’s insurance rules and consumer protections are administered by the Wyoming Department of Insurance. While insurers vary in how they treat diminished-value claims, the Department can assist if you believe an insurer acted unfairly. Always review your own policy for any language about limits or exclusions.
Helpful Hints
- Collect evidence right away. Photos and repair records are strongest when obtained immediately after the crash and repairs.
- Get at least one independent appraisal early. An appraiser’s early report strengthens your negotiating position.
- Use local comparables. Vehicle markets vary by region—local comps carry more weight than national averages.
- Keep copies of everything and a clear timeline of events and communications with insurers and shops.
- Ask repair shops if they performed structural or frame repairs; those repairs usually cause greater diminished value.
- Be realistic. Some older vehicles with low market value may generate small diminished-value numbers that fall below litigation or recovery costs.
- If the at-fault insurer refuses to negotiate, file a consumer complaint with Wyoming’s Department of Insurance (see https://doi.wyo.gov) before filing suit; often the regulator can help get a review.
