Dealers and consumers alike have a new tool at their disposal to safeguard themselves against buying a car that was previously wrecked and rebuilt. A 2009 law, pushed by NADA and other dealer organizations, requires insurance companies to share their data on totaled vehicles with a Justice Department database called the National Motor Vehicle Title Information System (NMVTIS). The database is available at http://www.vehiclehistory.gov/ and will permanently red-flag severely damaged vehicles.
