Not car related I know but, a federal attorny I know gave me this site. You can check to see if the FBI has ever had a file on you through the Freedom Of Information Act.
Was shocked to see there was a file on me. Do not use your SS number, just check your state, and put in your name. If a match is found they will ask for a year of birth to narrow the search. You will get a case number, date of investigation and any photos on file. Also list any misd/felonies etc. The search is currently available and free but the FBI is trying to get it shut down.
