I'm not sure where you're seeing the Lincoln "grille" through the mesh. If anything it looks more like the Fusion and the new Fiesta from the front end. However its possible that it might be a muled up Lincoln, however that seems extremely unlikely at the moment give the fact that the MKC went from being a C30 esk hatchback to a Lincoln Escape instead.
There was supposed to be a Mercury version of the Focus, to be named the Tracer but that was killed off with the brand.
The fact that it was on the back of a truck instead of being driven around could also lend creedence to it being either a freshly built mule, or a car on the way for the scrap heap.
We will need to wait and see if something comes out of those rumors.
