How bad is this?

From what I see in the picture and what I have experienced that car didn't take a bumper shot. Pull the quarter and try straightening whats there. . This car was hit the same way both sides. We straightened it and kept the panels. Its called metal work . The quarter must be stripped of all paint and filler. That is why I asked how much bondo ia in the car. If they would cut the quarter off before the car is straightened then they don't know what they are doing.

Start looking at the gaps and the roof that upper body was tweaked. I don't believe the frame was unless the upper body shot pulled it up.

The car should be set on a fixture for a 108 wheel base set up as seen in the picture that my Demon is on. The only thing that has to be removed from the car is the bumpers . There are pin holes in the frames where it sets in the stands put there from the factory. Find a resto shop with a fixture for your body style.
