Just seen this as I was browsing.
There seems like an awful lot of damage here, especially structurally to roof which even if the panels are repaired, surely the occupant zone will not have the same strength (offer same protection)?

Not an expert but when I hear CAT D .... I think of a wing or a door, not this level of damage.
