Buying a used car can save you money but also comes with risks. Finding out the history of the car is vital to help guide you in your decision. Did you know that the Department of Justice offers a website where you can find out information on the history of a car? For a small fee, the National Motor Vehicle Title Information System can tell you if the odometer has been tampered with and possibly even if the vehicle has been involved in a collision. The National Insurance Crime Bureau also has a website where you can obtain free information to see if a vehicle had previous flood damage which could mean the airbags and electrical systems are compromised.
