Base models and Esprits didn't get the screaming chicken, only Trans Ams.
I know, but that's kind of the point. Why was it so rare to put that kind of decoration on a car? I thought it was cool as a kid, and I still do, but most cars ever since have just had bland monochrome bodies, or maybe the occasional racing stripes.
Of course, in several Asian countries, they have vehicles custom-painted with incredibly intricate artwork, like the jingle trucks of South Asia and the Japanese dekotora. I think they have them in Africa too, if I remember right from the Sense8 TV series. I guess there's some American tradition of painting vehicles, notably the sides of vans, or hippie buses or stock cars. But actually selling cars with a standard artwork like the Firebird emblem is just not done anymore.
