Cinquecento Planter. Leitz Summitar 50mm

On my peregrinations through the City of Cambridge, MA, I discovered this treasure parked on a busy street.  It seems to have taken root - as it were -  with the blessing of the traffic department, and the luggage rack repurposed as a planter.  I knew it to be a FIAT Cinquecento, but Wikipedia had to fill in the details: this is a 500C, made from 1950-1955, the convertible available from 1954.  A couple of Extras serve to flesh out the scene.
