Matching numbers means THE engine the car came with from the factory.
I tend to agree but I think this "numbers matching" word is a paradox in the car collecting arena.
This reminds me of former president Clinton's famous quotes:
"I didn't inhale"
When asked about a sexual relation with Monica "It depends upon of what the meaning of the word... is..is"
I do remember reading somewhere a case where a buyer bought a "numbers matching car" and later found it was a restamp and took the seller to court. The seller was not found guilty because numbers matching didn't mean original. So "numbers matching" is a play of words, IMO.
After getting back into this hobby late last year I have done a lot of reading catch ups and the topic of restamps caught my attention and the seemingly wide spread use of it because of that human addiction called greed. But I can't help ponder, what is accepted and what is not, has come down to a pick and choose acceptance in his hobby. I mean, you can now get date coded glass and tell a potential buyer it's original glass. Nobody gets uptight when someone says I got dated glass, hose clamps, wires, etc... but a VIN or other date codes (alternators and distributors), then the conversations gets explosive. What is the real case here...the act of restamps or the potential value that can be obtained from a restamp that causes a pick and choose practice?
In the case of this so called Yenko, it's out right fraud. But this hobby needs to get a clear legal definition of what a 'numbers matching' car is so the word game semantics can stop and potential buyers and sellers know what is legally correct in definition and what is not.
Just my 2 cents
