Actually, my wife and I are involved in a similar situation, except in our case, some idiot piled into four of us while driving 50+MPH! Then, even though they were cited by the Police, they have decided to sue everyone they HIT!!!
We had the car fixed, got a rental, and both of us have to go through rehab 3Xweek (I had an MRI that shows a partially ruptured disc in my back). Go through insurance....it's not like it was her fault.....
