The issue with the '57 Funny is that it is a '57 funny! Only a couple of folks had that body, and only McEwen was the big name that ran it. Otherwise, it is a chassis donor type kit. I only see folks who missed out on the last issue getting it. I know I'm not, as I already have a few and have yet to finish even one!
And yes, I think the Green Elephant is selling mostly for the new decals and then secondary would be the scale. The Jungle Jim will sell at first, and again, for most of us 1/16th types, as a donor kit for different decals.
