Very interesting topic.
I am not familiar with the quality of the Classiche certification, but, if reliable, I think in some markets, like in Italy, it is a big plus for buyers, maybe even more appreciated than a complete documentation related to maintenance.
In Italy there are four certification 'entities' recognized by the State and by the Insurance companies: ASI (which is for every brand, Italian or foreign), RIAR (Alfa Romeo), Registro Lancia and Registro Fiat.
The three Registers are by far more severe than the ASI.
I have direct experience with the RIAR and I can assure you that you will not get that certification if your car is not fully original, down to the type of screw or the type of clamp used. Not even after market optionals of the right type and era are accepted.
You can't even change the original color of the car/interior if you want the certification (or, if they were changed, maybe by the previous owners, you have to restore them).
The Italian collectors usually prefer a well preserved car to a fully restored one. I think this is the opposite of the way in other Countries, where even well preserved cars are usually over-restored and often transformed in "candies on wheels", which looks like brand new cars, except that the car, even when new, never looked that way !
In Italy a vintage car with its original license plate, everything else equal, is worth 10-15% more just for that.
Another thing I find funny is that foreign experts of an Italian brand think they know more than the official historical register of that brand in Italy, which has access to all the original documentation (even documents never made public) and, often, to still living witnesses of the time a specific model was designed and produced.
