What a difference a brand makes. Where Ford is pushing its Fusion sedan as a street machine, Mercury is casting its Milan in the title role from "Here's Boomer" (1980s TV reference alert). The company is spreading kindness in the name of Milan in several cities with random acts of delight, like a free coffee or a manicure en gratis. The acts will take place between now and mid-November, during which marketing assistants will descend on Philadelphia, Boston, Atlanta, Austin and San Diego for two-day "invasions" (their quotes) that will include free beverages at morning drive, appetizers in the evening and salon services on Saturday. Oh, we get in now. Fusions are for boys and Milans are for girls. We totally did not see that coming.
