matching numbers?

"Numbers Matching" is a phrase that has become so generic, you need to make sure that it means what you think. If you really mean numbers matching, this only applies to cars built in the 68 model year or newer. That is when the manufacturers started stamping at least a partial VIN in big ticket items like engines, trannies and rear ends. The value of these cars, like previously stated is driven by the rarity of the original equipment and the ability to verify the correctness of the information. For example, a numbers matching big-block Dart GTS would be a whole lot more valuable than a numbers matching 318 version of the same model. Prior to 68, numbers matching really has little meaning. Since there is not the VIN relationship, this generally means that the major components are within the reasonably expected date codes for the car's assembly date. For many of the more collected/scrutinized models (Mustangs and Vettes for example), there are guidelines for the time frame differences between the component date codes and the assembly date.

So in short, the more common the model combination, the less impact there is on value for matching numbers. Hope this helps. L8r
