1. Review the report for factual errors first
Start with the easy wins: wrong trim, wrong mileage, missing options, or an inaccurate condition rating. Factual errors are the fastest thing to get corrected, and they don't require any negotiation — just documentation.
2. Research comparable vehicles yourself
Look for a handful of genuinely comparable vehicles — same year, make, model, similar trim and mileage — currently for sale in your area. If your own research consistently lands above the insurer's number, that's useful evidence.
3. Document your vehicle's actual options and condition
Photos, service records, and a list of factory options can support a higher valuation if the report undercounted them. The more specific and verifiable your documentation, the more persuasive it is.
4. Put your disagreement in writing
A written request — referencing the specific report, the specific errors or omissions, and your supporting comparables — creates a paper trail and is generally taken more seriously than a phone call alone.
5. Consider an independent valuation or appraisal
If the insurer doesn't move after a documented request, an independent appraisal can put a professional, defensible number behind your position. This is where a company like Synergy Auto Appraisals typically gets involved — reviewing the file and telling you honestly whether the offer holds up.
6. Check your policy's appraisal rights
Depending on your policy and state, there may be a formal appraisal clause that lets a value dispute be resolved by independent appraisers rather than escalating further.
