Very sorry to hear this.
Recently I had similar kind of incident.
It was a very slow moving traffic(due to some traffic block), speed will be around 0-10 kmph. Suddenly the car behind me rammed by car.
![Cry [cry] [cry]](https://www.theautomotiveindia.com/forums/images/smilies/Cry.gif)
called the MASS and asked about the cost of repair. They gave me an estimate of 4.5k. But the guy was not willing to pay the amount(even though his behavior was good and he accepted his mistake.). Instead just rolling and saying max he can do is 2k as compensation.
Since its was a heavy traffic block, there were enough police officers around. So I met the SI and asked about registering a case. His reply was, its better for you to get the amount that you can get from them. Or else he just need to pay something around 1k as fine so as to close this case unless nobody is badly injured. Also I have to keep the car in the police station and have to pay around 1k for the vehicle inspection charge for inspecting the damages.
Finally after a great talk I got 3k from him.(Since the guy was very polite, I had no intention to charge a case against him.)
So I think going to police station is not going to help in getting money as compensation. Anyways all the best and do update.
You got any pics of your car showing the damages, whats the estimate cost?
