I read the thread and was initially thinking $6K - $7K since it looked like 3 different panels. My wife's Expedition was fixed this year after a driver with no insurance hit it, that was $5500 and looked like much less damage.
It's quite a racket with auto insurance claims. The body shops know that insurance is paying, so they inflate the costs and order lots of new parts that don't really need to be replaced. I used to have a friend that worked as a body shop estimator and the first thing he would ask is: Are you paying, or insurance? If I was paying, he would be disappointed, but the price would be around 25% of the insurance price. That also partly explains why insurance rates are so high.
