Insurance companies are in the business of "insuring" cars. They do not buy and sell cars. That is what car dealerships do. Drive your car to your dealership of choice. When you choose a new car, you can turn in the old one to them. They will apply the value to your new car, or you can sell it privately. I recommend the former since repairs seems to be an ongoing issue. You could find yourself in legal trouble with the buyer. To protect yourself, hand over all of the repair bills so they can see what has been done. You have to sell it honestly.
