VIN Decoder: Check a Used Car's History Before You Buy (Why Dealers Hate This)

VIN Decoder: Check a Used Car's History Before You Buy (Why Dealers Hate This) I've been in the car business for 30 years. In that time, I've seen exactly three types of used car buyers: those who check the VIN, those who get screwed, and those who do both—usually in that order. Here's the truth nobody wants you to know: a 17-character VIN tells you almost everything about a vehicle's past. Recalls. Accidents. Flood damage. Odometer rollback. Whether the transmission was replaced. Whether the car was totaled and rebuilt. All of it. And dealers? They'd prefer you never look. The VIN Decoder: Your Free Weapon A VIN decoder is exactly what it sounds like—a tool that reads those 17 characters and pulls the vehicle's history from government databases, mainly the NHTSA (National Highway Traffic Safety Administration). In the US, this data is free and public. Same goes for Canada, EU, and most developed markets. The first 3 characters tell you the manufacturer. Character 10 is the model year.
