...ended, the impact sent me over? I have a Toyota Corolla 2007. About 6 wks ago I got rear ended, the impact sent me over the medium unto uncoming traffic. After all was said and done the car had $6,300 on repairs done. It came out okay but know I have trouble closing the trunk, I really have to slam it and the right side back lights don't really align. I am trying to figure out how much they will give me for devaluation value on the car, I have never done this before I want to make sure I don't get ripped off. Also I am still experiencing back pain from the accident, my primary doctor wants to send me to a chiropractor which my insurance doesn't cover, should the other insurance pay for it? They are not returning my calls, and they just want to offer me $500 for pain and suffering as long as I sing some papers that release the other driver and the insurance from any further responsibility. By the way it was the other drivers fault, she was in her cell phone hit mt at 45 mph from behind and this was her 10th accident in the last 3 mos.
