While Italian sports cars get a bad rap for being fickle, nobody has ever accused the Porsche 911 of having major reliability issues, and J.D. Power, publisher of the legendary reliability rankings, seems to confirm that, having named the 911 the most reliable sports car and Porsche as the top German manufacturer.
While some of Porsche's newer vehicles have been afflicted with engine problems, J.D. Power still gave the brand top marks, likely since its owner survey is based on the opinions of people who forked out good money for their cars. On the other hand, a Canadian study recently showed that 97.4 percent of Porsches from the last 25 years are still on the road, a testament to their longevity and robustness. Only time will tell if a current Boxster, Cayman, Cayenne or 911 will be as resilient.
