Ok, I asked some of my guys and nobody could really come up with something other than maybe contacting your insurance guy and seeing if he/she can find out more about the car. He/she may have access to some database or know a number for some type of agency that tracks that sort of thing.
Carfax report doesn't go into detail about the severity of the wreck? Maybe you could ask the police department (if known) where the wreck occurred and see if they have anything.
Sorry I couldn't be more helpful.
