Definition

The term "number matching" (or "matching numbers") is a term used in the collector car industry to describe the authenticity of collectible or investment quality cars. Number matching generally means that a particular car still contains its original major components or has major components that match exactly the major components the car had when it was new. These "major components" are not always agreed on. The appearance of a number matching car likely could not distinguished from an original car. A site by the name numbermatching.com (direct link removed since Firefox reports this site as "suspicious." Visit at own risk) has established a standard of specifications for a common definition of "number matching" and can certify them according to their company's definition.
