When you are involved in a collision, you will report the claim to either to your own insurance company or the insurance company of another at-fault party. The insurance company will assign a damage estimator to inspect the damage and write a repair estimate. Once the estimate is written, the repair cost will be compared to the value of the vehicle. Generally, insurance companies will declare a vehicle to be a total loss if the cost of repairs is more than 70% to 80% of the vehicle’s value.
If you have been informed that your vehicle is a total loss, the insurance company will then take usually a couple of days to determine the value they are going to offer you. During this time, you should do your own research to determine the fair market value of your vehicle.
Now when the insurance company makes you an offer you will know if it is within a reasonable range or not.
Now that you know what your vehicle is worth and what the insurance company is offering you, it is up to you to negotiate if the offer is not reasonable. You can start by sending the documentation you collected in step 2 above and making a demand of what you are seeking to settle the claim. If the insurance company does not properly negotiate with you then you may have to hire a professional vehicle appraiser to properly establish the value of your vehicle.
