Porsche Tops in Dependability

2010 Porsche 911.

Jaguar executives are most likely sitting around sighing and saying, “It was nice while it lasted.”

They would be referring to the fact that Jaguar, in a tie with Buick, was at the top of last year’s Vehicle Dependability Study from J. D. Power & Associates. It was a particularly sweet victory for Jaguar and Buick because they had edged Lexus from first place, where it had ruled for the previous 13 years. But in this year’s Vehicle Dependability Study, released Thursday morning, Jaguar plunged to 23rd place.

Porsche, meanwhile, was the highest-ranking brand. “The 911, the Boxster and the Cayman all performed well,” said Dave Sargent, vice president of automotive research at J. D. Power. “The 911 is one of the better vehicles in the industry.” It also helps that the 911 represents 60 percent of Porsche’s sales.
