Built 1/21/72 for the US so a little rare that it has vinyl, it would be very common if Canadian delivery which it is not.A photo of my presumed original vinyl herringbone pattern seats. Car is a relatively early 1971 North American delivery 3.0CS. Sorry for the lousy image. I happened to be sitting in the car during the end of the auction and was texting with @Markos at the time.

By the way, the vinyl is pretty supple.
