The car had cut pile when I bought it around 1990/1991. It was not the original carpet. I was the 3rd owner. Owner # 1 had it a year, then traded it back to the dealer. Owner # 2 owned it from late 1972 until he sold it to me.
Based on the early build date, I was leaning on the 80/20 loop. Hopefully I'll have a few more join in on this post.
Yote what is your build date?
