I don't think it has been in that type of accident, the lines are very well matched. As for the grille, it could simply have been custom painted, not all that uncommon. the lines do narrow from the pics I have seen in brochures & online images.
Good q on the airbag deployment. IDK if it is mandatory to be reported in those cases. Ford could probably tell by digging into the systems, not sure a dealer could, unless there are markings that tell you that the airbag was installed during production. And there are multiple air "bags" to examine, in that case.
