Well you can have a couple of independent estimates of repair verses the value of the car including a higher value then the blue book value of the car depending on the condition, mileage, special edition, special features, limited availability etc., and can press your claim. If they think the totalled car is worth pennies you can choose to keep it and they will have to pay the balance and you can sell the car separately for a higher sum or use it as parts etc., good luck.
