Some thoughts:
How many Camaros have been sold in the past with missing trim tags?
I've seen a few over the years......
How many Camaros have been sold with switched trim tags
that we are only now able to spot? Probably a lot more......
My suggestion would be to contact the seller and let him/her
know the trim tag discrepancy. If the car sale
still follows through, contact eBay and suggest that they
inform the purchaser that this car is questionable.
However, you can see that the seller could feel that this
is an infringement on their right to sell the car ( even
if they did intend to pass off a fake ). But, what if the
seller is trying to unload a bad purchase? Ever been in
that situation?
Lastly, and only playing devil's advocate here - even if eBay
was contacted about this car being questionable, how should
they proceed. What proof do they have that the tags were
indeed switched? The word of one of us? Perhaps we could
contact them as a group ( possibly carry more weight ).
I understand the issues here. But eBay is in business to make
money and that as they say - is that. I doubt eBay would
care unless we could prove that Adolf Hitler, or a senior
member of the Nazi party owned this car...

Forgive
the analogy, you see my point.
