The original "double image" that had me start this thread is now protected/removed from the original site, so I basically deleted my commentary now. Links to the other images of (what may be) the same car, are now in a new thread: Red w/carbon 2.5 advertising car images
isn't that Elon's garage? the left side looks similar with the landscaping. I think you're right on the overlay image though. I wonder if someone did it by mistake then everyone else just plucked up the image to use in their own articles.
To my eye, (a) the black band on the side mirror in the 1st and 4th match but is different from the 2nd and 3rd and (b) the hood "T" is white in all but the first. In think (b) is just the lighting, whereas (a) I'm not so sure.
