The Porsche 911 is arguably one of the best sports car ever made. It is true the 911's appearance has rarely changed since it's never had a major cosmetic redesign. Instead, Porsche has mostly focused on the engineering which has led the 911 to undergo dramatic mechanical changes throughout the decades. Each new generation of the 911 caused controversy among enthusiast who say the 911 is loosing it's purity. All I know is the 911 just get's faster and faster.
