Well all,
I don't have too much graphics experience but if I could get some time this week, perhaps I could put something together... I at least know some people that could help me.
I will see if I can't come up with something formal soon but since we all congregate at this site, I was thinking of something that would tie in to this. I would think the badge should be a standard 3" diameter round badge (76.2mm) with two studs on the back for mounting through the grille.
Around the edge of the badge would say something like "International W116 Enthusiasts Group - The First S Class" and then a logo in the center...
Again, the price would be $23.50 USD and $29.81 AUD not including shipping... However, I work for a company that gets a great discount on international shipping so it should be fairly reasonable...
