Porsche Top Brand in J.D. Power and Associates Dependability Study

Has Fewest Problems of Any Manufacturer

ATLANTA - March 18, 2010 According to a quality study by J.D. Power and Associates, Porsche continues to meet and exceed the long-term quality demands of its customers in the United States.

Porsche recorded the top score of all brands surveyed in the J.D. Power and Associates 2010 Vehicle Dependability Study(SM).

The study measured problems experienced by original owners of three-year-old (2007 model year) vehicles, including 198 different problem symptoms across all areas of the vehicle. Overall dependability is determined by the level of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality.

Based on this measurement, Porsche had the fewest problems and was the top brand in this important dependability study.

"For Porsche this is very significant," said Detlev von Platen, president and CEO, Porsche Cars North America. "It confirms that our cars meet the full spectrum of our customers' very demanding expectations well into the ownership experience."

According to J.D. Power and Associates, among new-vehicle shoppers, perception of quality and dependability is the most influential factor in their decision to purchase a specific vehicle model.
