I am intrigued that you saw a 1984 WE4 box for sale anywhere in any form. The reason is this, I had in my possession all 750 WE4s before I shipped them out to individual customers. None had the outer shipping boxes except the one I explained about earlier. It couldn't even be a car that was held back from the normal run by GMP, they didn't have any. The only explanation I can figure is that when I got my first off the line sample overnighted to me, GMP probably did the same. When GMP went under they sold everything they could and perhaps that one was still there. Had I seen it for sale, I would have bought it. What is it really worth? I have no clue, but I now know of only mine and the one you speak of.
