I wouldn't say it's a "smart junkyard" per se, look at the cars in the background. I bet it's a scrap yard across the pond, and since smart has been around since '98 out there it wouldn't surprise me to see old smart metal out there.
Maybe smart's recycling program started with the 451?
It looks like those cars have been parted out, parts of those cars are probably living on in other smarts. I'd gladly take two seats (awesome bedroom seating!) please.
