Diminished value · TRUEAUTO GUIDE

What documents help support a diminished-value appraisal?

A repaired vehicle may still raise a value question. The strongest starting point is a clear record of the vehicle before the loss, what happened, and exactly how it was repaired.

Identify the vehicle and the relevant dates

Start with the VIN, year, make, model, trim, major options, date of loss, mileage at the loss and current mileage. A registration, window sticker or build sheet can help resolve equipment differences. If the vehicle changed hands or accumulated substantial mileage after repair, note when that happened rather than treating today's condition as the pre-loss condition.

Keep the entire repair history together

Send the first estimate, every supplement, the final itemized repair invoice and any documented scan, calibration or structural measurement reports. Those records explain the actual repair scope more reliably than the initial estimate alone. Include the repair facility's completion date and any work that remains open.

Describe prior history accurately

Prior damage or repairs can affect the analysis. Disclose what you know and provide the related records if available. Do not assume that every repair line has the same effect on resale value, or that the entire difference between two asking prices is caused by one accident. A defensible appraisal needs to separate the collision at issue from age, mileage, condition and earlier history.

What a market review should explain

Useful support may include dated listings, actual market observations, vehicle-history information and an explanation of differences in trim, mileage, condition and repair history. Listings are asking prices, not completed sales. An appraiser should state the sources, assumptions and limits of the conclusion rather than apply an unexplained percentage to the repair bill.

Start even if the file is incomplete

The VIN, loss date, mileage and final repair paperwork are a useful first submission. TrueAuto can tell you which missing records would materially improve a vehicle-specific review.

Before you submit

Check the claim and policy context for your state, then send the documents you have through the claim intake. Whether a claim is available or supportable depends on the facts and applicable rules. A preliminary review is not a completed appraisal or a guaranteed recovery.
