I had almost the same thing happen to me several years ago. My new Sierra with 1700 miles on it. A guy pulled from a side street into the side of it as I was going down the road and ripped the side off my truck from the front door back resulting in over 17,000 in damage. My insurance company told me to file a claim with his insurance after the truck was repaired for 1/3 of the amount required to fix it. They did pay the claim without me having to hire a lawyer. State Farm told me that this was considered the norm for these cases.
