German Technical Inspection Agency, TÜV, has reported the Porsche 911 was the most trouble-free of any vehicle in its age group for the second year running. Regardless of being seven, nine or eleven years old the 911 registered in general technical inspections the fewest defects among all vehicles.
A testament to the long-term quality and strong residual values of all Porsche models, the 911, Boxster and Cayman models held five of the ten best rankings across all age groups.
The TÜV report compiled data from approximately eight million general technical inspections conducted between July 2010 and June 2011. As a result, almost 18 percent of seven year old vehicles, 22 percent of nine year old vehicles and 26 percent of all eleven year old vehicles exhibited such serious defects that they only received their TÜV certificate the second time around.
