My VIN Decoder site, Decode This! has broken the 100,000 decoded VIN marker.  This is a marvelous accomplishment.  When I launched the site a little over a year ago I never imagined I'd see it used to that level.  Check it out if you're interested in classic car or modern car VIN decoding.  What's a VIN?  A Vehicle Identification Number is a unique number assigned to each car at the factory.  Kind of like a social security number for your minivan.  It contains all kinds of information about your car, such as the make, model, year, and engine type.
