One Smart minicar in each of two areas--Cole Valley and Twin Peaks--was reported at wee hours of the morning to have been overturned while parked on the street.

The NBC affiliate didn't have any photos of the new outbreak of vandalism, but its photo gallery of the April incidents indicates the extent of the potential damage--which likely included scratches in the paint, dents in the body panels, and broken trim.

The two-seat cars, less than 10 feet long, are popular in crowded and hilly San Francisco because they can park in smaller spaces than any other vehicle sold in the country.
