Well, I was in the store watching toys for my nephew and suddenly I found this, this unopened.
You can tell by the scratched cardboard next to the last M in "Millennium" that somebody cut the bubble off with a razor blade, replaced the Falcon with the Enterprise, glued the bubble back on and returned it to the store.
The end of the Enterprise's stand should have a ball joint on it, but this one looks like it broke off inside the ship. I've had the same thing happen to me twice with Star Trek Hot Wheels. That's probably why the owner wanted to get rid of it.
