I have test-driven the new sleek and slender Porsche 911 Cabriolet Black Edition and found it incomparable on all accounts. The luxury two door sports cars come with world class interior features that set it apart from other models. Some of the features that make 911 Cabriolet interior worth a try are automated climate control system, air quality control, multi-functional steering wheel, rear reading lamp, rear sear armrest, power steering, power windows and much more.
