Fresh from its remake in 2005, the 911 continues to define Porsche. Though the sheetmetal has changed over the years, the silhouette has an unmistakable relationship to the original 911. Admired as much for its status as its speed, the 911 demands a premium price that is out of reach for most drivers. This relentless demand sustains a strong resale market, and the 911 retains a tenacious grip on its value.
