I’m sorry to hear about your accident and your totaled car. When your car is totaled, your insurance company will pay you the actual cash value (ACV) of the car. This is the pre-crash value of the car minus your deductible. They will also consider the wear and tear of the vehicle.
If you disagree with their assessment, you may be able to dispute the valuation. The best way to do this is to show that your car is worth more than what they are offering with evidence from similar vehicle sales at dealerships, as well as the Kelley Blue Book price.
