Sorry to hear about your accident!
There are some instances in which the insurance company will sell you back the vehicle—for example, if you’re planning on repairing the vehicle despite the insurance company’s evaluation or if it has sustained hail damage but the vehicle still works well. There are some states, however, in which you are not allowed to buy back a totaled car.
If you are able to buy your vehicle, you will receive a check for the payout, minus your deductible and whatever the insurance company may have earned off selling the totaled car.
