The scary thing is that it seems to have been done with no regard for the factory seams. I bought a wrecked low mileage Nissan Sentra a few years back and cut and welded it back together. I respected the factory seams and did almost everything with plug welds. I later wrecked the car again in a far more severe accident in the same place I had repaired. It held very well and none of the seams split. This is because it was put back together the same way it was assembled when new. Sadly, that would not be the case with this car. There is no stagger to the repair, just a clean cut line. In a wreck this is dangerous and would split apart as the weak point is uniform. If it were staggered in different places like a stock car would be, it would be about as safe as if it were never repaired. The rocker, for example, would be a single piece and extend in front of the toe board to floor pan seam that is there when the car is built. The roof pillar would have been secured better to the firewall, etc.
