These are named for famous Jeep trails or areas; Rubicon, Moab, Rocky Mountain, Columbia, Sahara or for other things; Golden Eagle, Renegade, Islander, Arctic. . .and so forth. They're identified by a strip decal on the side of the hood.
Shortly after the first special edition came out--the Renegade I think--the first parody appeared. Don't know what that was but there are a plethora of them now; Decepticon, Rubican't, Mall Crawler Edition and many others.
One that caught my eye was this one:

It's in a Native American Language, probably Cree, and refers to the Chequamegon National Forest in Northern Wisconsin, a popular 4wd area. Naturally I thought what we really need is a Welsh Edition!
At first I tried to come up with various areas in Wales to use but then realized it needed to be um, er, Pan-Welsh so I googled Welsh Edition and came up with both ARGRAFFIAD CYMRAEG and RHIFYN CYMRAEG. One means edition the other issue but I'm not sure which is which.
It's rather important that the sticker translate to Welsh Edition as I don't want to own a Jeep that has an issue.

So, ARGRAFFIAD CYMRAEG or RHIFYN CYMRAEG?
Oh, the sticker would also have an oval Welsh flag too.
Diolch!
