I don't believe it was cut, the car was in some type of accident but the rest of the car looks fine for the most part. Never noticed that last year, crack was probably hidden with that gunk on top when I bought it. I'll take more pictures
You understand that these cars have no frame, body is unitized. Unitized is just sheet metal welded together to form a rigid structure.
It all looks pretty normal to me. I would just add a strut tower brace.
