Glad you made it out alive, Chris.
I used to own an '86 BMW 325I. These things had light rear ends, and I had an event in it almost exactly as what happened with the Jetta when I merely tried to change lanes. I went around about three times. Bounced off a wall, and ended up in the ditch. I sold that ****** car as soon as repairs were made. It wasn't one of BMW's best balanced models, and many 325 owners put sandbags in the trunk to make up for it. Dumb!
