The 2006 Porsche 911, part of the legendary sports car's 997 generation, is an iconic high-performance vehicle complementing style with speed. It is available in four trims: Carrera, Carrera S, Carrera 4, and Carrera 4S. The Carrera and Carrera 4 versions are equipped with a 3.6-liter, 325-hp flat-six engine, while the Carrera S and Carrera 4S pack a more potent 3.8-liter, 355-hp engine. All models have a standard six-speed manual transmission, with five-speed automatic (Tiptronic) as an option. Expect 18 to 26 mpg depending on the model and city/highway driving.

Inside, there's a GPS-based PCM (Porsche Communication Management) system, featuring a 5.8-inch touchscreen, although modern amenities like Apple CarPlay and Android Auto are absent due to the model's age.
