Based on analysis of 66 911-Carrera reviews and test drives.
Reliability
The 2008 Porsche 911 Carrera reliability score of 10.0 out of 10 is the Predicted Reliability rating provided by J.D. Power and Associates. This score is based on trending the past three years of historical initial quality and dependability data from J.D. Power's automotive studies, specifically the Vehicle Dependability Study (VDS) and the Initial Quality Study (IQS).
Porsche offers a four-year/50,000-mile new car limited warranty.
Reviews don't mention any concerns about the 911's reliability. "Thanks to new technologies, materials and lubricants, nearly every scheduled maintenance interval has been lengthened, and that should increase convenience and reduce the cost of ownership," writes New Car Test Drive. "The maximum oil-change interval for the Carrera is an almost unbelievable 20,000 miles."
