That is a wagon door card for sure. It’s off an MB Tex interior as evident by the upper panel being the same material as the rest. The leather interior cards have a “puffy” insert on the top half.

If you don’t have a passenger side grey leather card, I’d possibly be interested in a pair of grey MB Tex cards if you have them.

Or if you have all 4 black cards. I’ll send you a message so we can talk more directly.

Thanks!
