Detailed Answer

Under Montana law, when you file a diminished value claim, you must show the difference between your vehicle’s fair market value before and after an accident. Courts and insurers look for credible, quantifiable proof. Below are the primary types of evidence that can strengthen your claim.

1 Certified Independent Appraisal

Obtain an appraisal from a certified auto appraiser who uses recognized methods such as the Market Comparison or Cost Approach. A detailed report showing pre-accident value, post-repair value, and the calculated diminished amount carries substantial weight.

2 Detailed Repair Invoices and Estimates

Collect all repair shop invoices, including parts, labor, and paint. Ensure invoices list each repaired component. Comparing repair costs to the appraised diminished value shows the severity of damage.

3 Photographic Evidence

Take clear photos of your vehicle immediately after the accident, during repair, and after repair completion. Include shots of damaged panels, frame alignment, and interior damage. Time-stamped images verify the extent of impact.

4 Pre-Accident Vehicle History Reports

Use services like Carfax or AutoCheck to generate a report dated prior to the accident. Showing a clean history before the loss emphasizes that any decrease in value resulted from the accident.

5 Comparable Market Listings

Gather listings of similar vehicles (make, model, year, mileage, condition) for sale before the accident. Use reputable sites and note sale prices. This demonstrates fair market value lost due to the accident.

6 Expert Testimonies and Declarations

Consider sworn statements from used-car dealers or automotive experts familiar with regional market values. Their declarations can support your appraisal and explain why buyers pay less for previously damaged vehicles.

7 Insurance Correspondence Records

Keep copies of all communications with the insurer, including emails, letters, and claim forms. Documenting offers, denials, and internal notes can help if you escalate to arbitration or court.

8 Vehicle Inspection and Repair Shop Reports

Include reports from pre-repair inspections, frame-alignment checks, paint thickness meters, or diagnostic scans. These technical data points highlight structural or hidden damage that affects value.
