Some backstory: My father has purchased this car for me at an auction and is giving it to his friends body shop to repair (he does this all the time). The car is a 2017 Infiniti Qx50.

We have purchased doors for the car already and they are going to start work on it soon, but I am getting a little anxious about it. I haven't had a chance to talk to the body shop about it but I am particularly curious about the bottom part of the b pillar, is that part fixable? Do any parts of the door attach to it? And also does it look like there is frame damage? It looks like everything came clean off the car but I can't tell for sure because the car is currently wrapped up. I also included pictures of the old doors for reference of damage. Please any advice will be helpful, thank you.
