Catch a first glimpse of the latest TV spot from Volkswagen of America not on the tube but on the computer. VW previews the commercial from Arnold Communications, Boston, today on vw.com. E-mails to 250,000 consumers and a page ad in USA Today alerted consumers to the premiere. "Milky Way" features the 2000 Cabrio and shows a group of friends mystified by a moonlit, star-studded sky as they drive along in the VW convertible. A mellow oldie, "Pink Moon," complements the visual -- Web viewers will be able to link with Amazon.com to buy the music.
