Dont settle for anything less than "NEW PARTS" on your car! I can almost guarantee that if you push them hard enough and tell them that you dont want to have the car fixed ( I mean who wants to have a car that has a replaced rocker and bent frame???) and that you want a new one or the cash...they will give. I had a similar problem with a Dodge mini van where the frame was bent and the engine heads cracked during an accident, and they wanted to fix the van at a local body shop.....HELL NO!!! I told them I wanted the cash, or a new van, so they gave me the cash.
As my old man sais...."cash money makes blind people see agian"!!!
