I know the car had an accident crashing in a highway off-ramp divider in the early '90s, so who knows. But it doesn't look like it had a hard life. The car is mint underneath. The cracks was in the sheet metal, not the actual shock mounts. I think this is just the softness of the SportsRoof chassis. The air shock theory is interesting to me. These cracks were in the car when I got it (2004), and they looked like scissor cuts more than anything. Looked to me like something that has been made over time. I think a sudden impact would have left a more drastic clues, or at least other damages to the area around it. In this picture, I had scraped the under coating, and pressure washed it. It was clean as can be. Can even see the assembly line dolly mounting marks at the rear. I added the subframe connectors in 2005, so the cracks was there before I did that.
