I would bet a weeks pay - it was some sort of parts failure. In other words - it got a lot of help.
I'm done looking for it and would be of no benefit to me to prove it to you that it happened. Other than your paycheck. I'll PM you my address when you get the info you need.
Anything CAN happen. Next time you are curious ask your BMW buddies if anyone remembers seeing them introduce the 3 (Maybe 5 series) wagon around 1997 and they flipped it during some spirited driving during the reveal.
