Aashish bro! I know people who have been in accent in which the other party took off. But I believe you should get more than the fair market value for your car. Which insurance company is supposed to pay you? Tell you what, you might wanna seek legal advice or even representation depending on the pre-accident value of your car, your post-accident trauma, bodily injury or so forth. You could legally be awarded good sum of money. I would recommend you to seriously look into professional legal counselling. I hope the accident afflicted you no physical injury and Good luck. TM
