Luckily, she was very forthright and up front about it all, had all her info (more than I need, really) written out for me before I even asked. Not much damage, honestly, just the rear bumper half-collapsed, a tail-light lens cracked, and a small dent in the rear door which did not affect its operation. No harm to us, airbags didn't even go off (thankfully!). Just really annoying.
On the other hand, I don't have to worry about when the first 'ding' to the new car will be!
