Your insurance company should give you the value of whats the cars worth (if you have full coverage) if its totaled. With what they give you buy used parts and fix it yourself if there isnt major damage I know you dont want to get rid of the car. This happend to me except i was rear ended by some idiot lady with no insurance. She hit me from a dead stop and sent me into a car infront. So we were going to have her sign a contract that says shes going to give us a sertain amount of money till she pays off the damage. If she misses a payment we sue..........of course my parents didnt make her sign the contract so we got stuck fixing the car.

I did all the work, besides paint. Total cost was $590 with paint
I needed hood, rear bumper, and front bumper. Most of the paint cost was the hood. Its a custom black pearl
Even if the damage is really bad just try and fix it the best you can
