Both cars provide impressive power utilizing 6-speed gearboxes and offer top of the line performance handling. These exotic cars offer excellent and comfortable interior space and even when the space seems limited, the passengers won't feel cramped.
Let's talk about the exterior. The Carrera S4 has a finish that is at a premium level, in and of itself, and surpasses the Ferrari 430 which is still impressive with carbon fiber, aluminum and a combination of suede in the interior. Although, the Germans excel on the finish, the 911 Carrera S looks like a 911 and doesn't bring as many ooohs and ahhhs as a Ferrari does when it comes to appearance. Ferrari's just generate more attention possibly due to their rarity on the road and higher price. Nevertheless, most people, if given the opportunity, will not pass up the Ferrari F430 if they had the cash. In the end, they just may do that because of the Porsche 911 Carrera S having a more complete package but you can always test drive your favorite exotic sports car and make your own decision.
