This stinks...glad no injuries occurred.
I'm curious to see if they want to replace trunk pan. The first place I took ours to totally screwed us over. In the process of finding a shop of my liking to fix rest of what wasn't fixed. Anyways, the guy there insisted that the factory welds are way stronger and beating it back into shape was better than replacing.
Good luck on the fix, hope it's a quick one and up to your liking.
