Detailed Answer – How to Prove Diminished Value of a Car in South Dakota
Below is a clear, step‑by‑step explanation of the documentation and appraisal process you’ll need to prove diminished value (the loss in a vehicle’s market value after damage and repair) under South Dakota practice. This is informational only and not legal advice; consult an attorney or contact the South Dakota Division of Insurance for case‑specific help: https://dlr.sd.gov/insurance/.
1. Understand what “diminished value” means
Diminished value is the difference between your vehicle’s fair market value before the accident and its fair market value after repairs. Even when repairs are cosmetically perfect, buyers often pay less for a vehicle with an accident history. You can pursue diminished value from the at‑fault driver’s insurer (a third‑party claim) or, in some cases, from your own insurer depending on your policy.
2. Gather baseline evidence of pre‑loss value
To prove a loss in value you must show what the car was reasonably worth immediately before the accident. Acceptable evidence includes:
- Vehicle valuation reports from recognized guides or services (Kelley Blue Book, NADA, local market listings). Use multiple sources and save printouts or screenshots showing date, mileage, and condition.
- Comparable sales (ads or dealer listings for the same year, make, model, trim, mileage, and condition in your local market).
- Dealer appraisal statements or trade‑in offers made before the crash, if available.
3. Document the damage and the repairs thoroughly
Insurers and appraisers will want to see a complete paper trail:
- Clear photos of the vehicle before the accident (if available), immediately after the crash, and after repairs (multiple angles: exterior, interior, and any area of structural repair).
- Police report or accident report that documents the event and the at‑fault party (if any).
- All repair estimates and final repair invoices showing parts used, labor, whether structural/frame repair or airbag deployment occurred, paint work, and who did the work.
- Receipts for replaced parts and any receipts for aftermarket parts or upgrades that may affect value.
- Vehicle history report (Carfax, AutoCheck) showing the accident entry—this is frequently the single biggest driver of diminished value in the market because it shows an accident flag.
4. Get an independent diminished value appraisal
A standalone diminished value appraisal prepared by a qualified appraiser provides the direct comparison of pre‑loss and post‑repair market value. When selecting an appraiser:
- Choose someone with experience in post‑accident valuation (look for appraisers who provide a written methodology and market comparables).
- Ask for a detailed written report that shows: pre‑accident value, post‑repair value, the methodology used (market comparables, cost approach, or other), all supporting photos, and an explanation of adjustments for mileage, condition, and locality.
- Confirm whether the appraiser uses standard formulas (some use the so‑called “17c” style or insurer formulas). Note that insurers may have their own internal valuation methods; an independent market‑based appraisal that shows comparable sales is often persuasive.
5. Prepare a claim package and present it to the insurer
When you make your claim for diminished value, include:
- A cover/demand letter explaining the claim and the amount sought.
- Your independent diminished value appraisal and all supporting documents (photos, vehicle history report, repair invoices, pre‑loss valuations, and comparable sales).
- Copies of the repair shop’s estimate and final invoice showing repairs performed.
- Any correspondence with the at‑fault party or their insurer.
Send the packet by certified mail or via the insurer’s documented claims portal so you have proof of delivery.
6. If the insurer denies or undervalues the claim
Options include:
- Request a written explanation of the denial or the valuation methodology.
- Obtain a second independent appraisal or multiple appraisals to strengthen your position.
- Use any appraisal or dispute resolution procedures set out in the insurance policy (some policies include appraisal or arbitration clauses).
- If informal negotiation fails, consider small claims court, formal litigation, or hiring an attorney who handles insurance/property damage claims.

7. Timing and preservation
Act promptly. Preserve all records, photos, and receipts. Insurers often investigate value soon after repairs; waiting long can weaken your claim. If you plan to sue, statutes of limitations apply to property damage claims—consult an attorney or the statutes to determine applicable deadlines for filing.
Helpful Hints — Practical Checklist to Prove Diminished Value
- Keep an organized file: police report, photos (before/after), repair estimates, final invoices, and all communications.
- Get at least one independent diminished value appraisal that explains its valuation method and includes comparable sales.
- Collect pre‑loss evidence: KBB/NADA printouts, dealer trade offers, or contemporaneous ads for similar vehicles.
- Purchase a vehicle history report (Carfax/AutoCheck) and include it in your claim packet.
- Ask the repair shop for a written description of any structural/frame work, replaced parts, and paint/finish work.
- Request the insurer’s valuation in writing and ask them to disclose the method used.
- Send your demand and documents by certified mail or through the insurer’s claims system so you have proof of submission and dates.
- If the insurer relies on a formula (e.g., an internal discount table), ask for the source and an explanation in writing.
- Consider getting multiple appraisals or a dealership appraisal if you intend to sell or trade the vehicle soon.
- If the insurer refuses to pay and the amount is significant, consult an attorney experienced in auto/property claims for South Dakota matters.
