Diminished Value is the loss in vehicle actual cash value (ACV) after it has been in an accident.
While there is no perfect science to this calculation, we use actual vehicle retail average sales to determine the value of a vehicle prior to the accident date and compare it to the value after the accident including any adjustment for mileage and damage repaired.
Diminished Value is offered when the ACV after the accident is less than the ACV prior to the accident.
The State of Georgia has required certain insurance companies to use a standard formula called the "17C" to determine diminished value.
