That was photoed by this blog’s setter-up Michael Jennings, last month, in Los Angeles. Presumably these cars were for some sort of movie or TV show. Whenever you see cars being carried about in lorries like that in London, that’s why they’re doing it.
I missed this photo when MJ first put it up at his Facebook site. But I encountered it more recently when an email incame, alerting me to another MJ photo. I liked that one, but then I scrolled back through all his recent Facebooked photos, and liked the above photo even more.
