Don't think I've seen it on an E34...well, maybe a special edition.
I could see Dove seats in a black interior car. You'd want to have all seats in Dove, WITH DOVE DOOR PANEL INSERTS.
That would be the way to do it. I'd do a black Alcantara headliner as well.
Sometimes I think about doing black seats and door panel inserts in mine, but I've got Parchment, so don't think it would look so hot.
