Sorry to see the damage.....best of luck!!
First thing that ran through my mind was: use your insurance company to fix the car and then personally sue the company for the amount they reduced your car's worth. A car in an accident is worth less than one that has not been in an accident.
But...lawyers cost money, there will be additional stress and possibly not as much compensation as should occur. Something to weigh.
Another thought.....go Carbon Fiber
could be a good alternative?
