A valuation report can look detailed while still containing a material input error. The correct approach is to identify the exact issue, show how it affects comparability or adjustments and provide reliable evidence for the correction.
Key point: Not every difference is an error. A useful audit distinguishes incorrect facts, unsupported assumptions and reasonable professional judgement.
Vehicle identification errors
An incorrect subject vehicle can affect every comparable and adjustment.
Wrong trim or model generation
Incorrect drivetrain, cab, box or body style
Missing factory package or equipment

Comparable selection problems
The lowest-priced vehicles are not automatically the best comparables.
Different trim, engine or drivetrain
Large mileage differences
Materially different condition or accident history
Listings outside the relevant market
Duplicate, expired or unavailable vehicles
Wholesale or auction evidence used without context
Adjustment and settlement issues
Adjustments should be understandable and applied consistently.

Frequently asked questions
Should I challenge every small error?
Focus first on material issues that affect the vehicle identity, comparable selection, adjustments or final amount.
What evidence proves the correct trim?
VIN decoding, the bill of sale, build sheets, manufacturer equipment records and clear photographs can help.
Can an appraisal report use imperfect comparables?
Sometimes. A limited market may require broader evidence, but material differences should be recognized and explained.
