Because of the fact that many of the reproduction parts
are getting so good today, knowledgeable people started
to point to the documentation as the only way to "buy real".
Now, we have better fake documentation. Then it gets aged
better to look more real. Now we have sellers on eBay
trying to sell VIN plates, cowl tags, etc.. You can all see
exactly where this is going - can't you? If the suggestions
made here are correct ( so many good fake cars ), what will
happen to the real cars? Only those known for many, many
years to be real will survive with high prices. I fear for
all the other real Z/28's, L/78's, etc. that have not been
"known" by and large. Those cars will be cast in doubt for
a long time and this will have to affect their respective
values.
