Search here and camaros.net on NICB. In short, it is a database for the insurance industry and law enforcement to check to see if a car is stolen. They just happen to have the selling delaler info on most cars. No other info seems to be available in most cases. The bummer is that they will not sell a consumer a report. You have to be in Law Enforcement to be able to access it, and even then they ask lots of questions. It seems to be hard to get a officer to risk getting in trouble to get you one.
