Anything is repairable. I have seen cars retored from just a bolt. The question would be if it was financially repairable.
If someone wanted to do $100,000 of work for free that's their business. I wouldn't.
It would be interested to see the quality or lack of quality that was done.
As far as wanting to own that car, I would prefer not to.
I find it difficult to believe that the current owner found the damage undetectable, but it is possible.
One of the values of a "World Registry" is to keep an independent history of vehicles to avoid misrepresentations on severly damaged vehicles, or title challenged ones.
Something to think about.
