The first step would be to check with your claims adjuster. You will need to know if they allow buybacks and how much the salvage value is.
For example, let’s say the actual cash value was $11,000 and you have a $1,000 deductible. Your insurer would issue a check to you for $10,000 if you do not want to keep the car. If you want your vehicle back, they will deduct the salvage amount from the claim payout. If the salvage price of the car is $6,000, you will get a check for $4,000 and keep your vehicle.
Once you have your car back, you may have some hoops to jump through if you want to get on the road again. Auction cars are issued salvaged titles. You would have to have your vehicle repaired and inspected for it to qualify for a rebuilt title. Every state has its own laws for this, so check with your local DMV for guidance.
Some insurance companies will not provide insurance for any cars that were once salvaged.
