It's been on this planet since 1963 and the Porsche 911 remains what many claim to be the quintessential sports car. Others can't stand it, but no one can question its influence on the industry for the past 50 years. As the old saying goes, "The more things change, the more they stay the same." The 911 has grown in size and gained power over the decades, but it has stubbornly retained its butt-engined flat-six engine layout. Some hate that fact while others applaud it, nevertheless the Porsche 911 will forever be an evolution of perfection.
