March U.S. sales for Volkswagen AG, Germany's largest automaker, fell 19 percent as fewer buyers chose its Passat and Jetta sedans, according to Bloomberg News. That led overall sales of European models to the fourth straight monthly decline. Sales of European brands fell 3 percent to 98,523 cars. DaimlerChrysler AG's Mercedes sales fell 10 percent, as Bayerische Motoren Werke AG and Porsche AG rose due to increased purchases of their luxury sport-utility models. "Volkswagen's products are just getting old and people are concerned about the quality," Art Spinella, president of Bandon, Oregon-based CNW Marketing Research, told Bloomberg.
