He could always just do his car buying without inviting a photo crew.
Photo crew? The photo looks like it was taken by a random guy on a camera phone.
Which is almost certainly exactly what happened - DC showed up and the owner thought he'd have a photo, which seems fair enough.
Who released it to the media - the PM or the used car seller? It's good advertising for his business, so why not make a thing of it?
I doubt it was intended to be a 'thing' otherwise it would have been a proper photo shoot.
