Oh man, so sorry you have to go through this. I had a "minor" rear-ender some years ago. I learned a lot in the process. Most important: pick a QUALIFIED BODY SHOP THAT KNOWS CLASSIC PORSCHES!! As mentioned above, the evaluation is critical for when you deal with insurance people, and you need an expert who knows these cars for that. It's important also because, depending on what is damaged, some inner structure parts are NLA (or not available easily in the US). The right shop will know how to obtain them.
As mentioned, please keep us posted. Good luck.
