Interesting...I'll need to check on my '93. I just assumed it was just molded grey plastic.
It looks and feels like it until you get an edge on it.
In fact, when I went out to look earlier, my first impression was that you were right.
I only looked again (and harder) because I'd remembered that my damaged area was cut rather than cracked.
The only place mine is soft enough to feel the difference is right under the radio/right over the ashtray lid (that's where mine got damaged).
