I think I have seen a wink mirror in a Europa. After installing one, you will no longer have visors if that's important to you.
I don't have my visors installed because I'm high enough in the car that they would be useless but I kept my visor mounts in case I ever got a wink mirror.
I have to say, I'm not terribly motivated to try one. I see pretty well with my Vitaloni Baby Turbo style mirrors and a clip on convex mirror on the interior mirror.
