Porsche 911 Reliability

You won't find Porsche 911 reliability information like this anywhere else. Actual repair frequencies, not just vague dots. So you can tell how much the Porsche 911 truly differs from competing car models in reliability.

These stats are promptly updated four times a year, to much more closely track Porsche 911 reliability as the cars age. Others tell you how reliable the Porsche 911 was a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the Porsche 911 has been recently.
