You’ll need to provide:
Your insurance company used a specific method to calculate your car’s value. You’re allowed to ask for a copy of the valuation so you can see how they arrived at the number.
Look up prices for similar vehicles in your area—same make, model, year, mileage, and condition. Print out or save listings to show your adjuster if your research shows a higher value.
Did your car have upgrades or features that might not have been included in the valuation? Things like a premium sound system, leather seats, or newer tires can affect value—so be sure to mention them.
