Here's my take on this. Based upon my research, I bet if you looked for stress cracks or signs of stress on any used 3-series you'd find it. We are alowed to magnaflux stuff and replace based upon signs of impending fatigue. How is a car body any different? It doesn't have to be catastophic failure, just failure, right?
