Diminished Value
Even if a vehicle is restored to its original condition, it will almost certainly lose value once it has been in a wreck. Buyers won’t pay full market value once they discover there’s an accident in its history.
Filing a diminished value claim with the at-fault driver’s insurance company can allow you to recover the difference between what a car was worth before an accident and what it’s worth after.
It’s up to you to present documentation about the wreck and make your case for diminished value. An accurate appraisal from Auto Mediator can help successfully prove your vehicle’s value.

Total Loss
In a total loss case, the insurance company will determine your car’s pre-accident value and offer a settlement. They calculate the amount based on make, model, mileage, and the car’s condition.
If you feel the settlement you’ve been offered is too low, you don’t have to accept it. You have the right to contest it.
A fully customized documented report from a professional appraiser will create a rock solid foundation to prove your car is valued correctly. Insurance companies have a harder time disputing a vehicle valuation report from a non-biased licensed appraiser.
