Matching numbers in my book should mean the engine and drivetrain components that the car left the factory with. But people are deceiving potential buyers with calling a numbers matching car one with correct castings and codes and restamps
. Today you always have to ask what the sellers definition of numbers matching is. It sucks that you really need to read between the lines. Whenever I have talked to sellers that seem knowledgeable about a car they are advertising it's always real interesting when they all of a sudden get stupid when you start to ask hard questions.
