During the 1970s, I recall seeing Superbirds every once in a while.
Once, back in the '70s, I spotted a *nose* of a Superbird laying in the grass near an intersection. It was orange, so there was no doubt it was from a Superbird. There had apparently been an accident at the intersection and the nose had been left behind.
I got home and called someone I knew who had a pickup truck so that I we could go fetch the Superbird remains. Unfortunately, by the time we got there some 45 minutes later, someone else had already grabbed the prize. Hopefully, it was the owner of the wrecked Superbird.
