Noooooooo ......my eyes deceiveth me! That actually looks like a tiny propeller at the bumper! Did it actually get turned by the wind as the car drove along or was it connected to the engine and turned by its revs?
I have to say some of these cars are really making me break into fits of laughter!
Some had me turning away and chanting mantras to ward off the evil eye (some of those cars must have been designed with demonic collaboration due to their supreme ugliness).
It just spun around in the wind. No purpose to it, it was just for nice.
