Will Car Insurance Pay for the Total Loss of a Rebuilt Title?
Generally, since the car has already been declared a total loss, the insurance company is under no pressure to pay for a total loss rebuilt title. If they do choose to pay for a total loss on a salvage or rebuilt, then you will likely find that the amount you get will be the difference between the amount already paid out on the vehicle and the amount the vehicle they put on it now. This means that if they have already put a zero balance on the vehicle, you won't get any money at all. If they put a value of a $1 on the vehicle, then that's the check you'll get.
