People getting defensive at car shows!

Went to a show tonight. Before I even get out a see a shaker hood car. So I immediately walk up and start looking. A lady and two guys were sitting in front of it. I take a pic of the fender tag. Lady immediately asks me what I'm doing and says why do you think it's fake? I say I have no reason to believe that I just like looking at sequence numbers, scheduled build date etc. she then informs me the car was built in October or November. . Here's a pic of the tag. The car was beautiful!

I was at a car show & a mate said some guys were messing with my tag,s raced over & they took off had 1 screw out .
Guess what tags are no longer on the car & the hood stays closed
