How to decode a Buick Reatta VIN

Characters 1-3 of a Buick Reatta VIN

The World Manufacturer Identifier (WMI) is the first three characters of a Vehicle Identification Number (VIN), uniquely identifying the manufacturer of the vehicle. For the Buick Reatta, an iconic luxury sports coupe produced between 1988 and 1991, the WMI is 1G4, indicating that the vehicle was manufactured by General Motors LLC in the United States. While each WMI is specific to a manufacturer and sometimes even to a particular plant location, the 1G4 sequence signifies that the elegant Reatta, with its distinct design and advanced features for its time, falls under the broad umbrella of General Motors’ extensive family of cars. As part of the VIN, the WMI plays a crucial role in tracking recalls, registrations, warranty claims, and thefts, establishing it as an essential mark of automotive identity.
