A classic among classics, the Porsche 911 is staying the course in 2017 by offering something for everyone. Versions include the coupe, cabriolet, Targa, Turbo, S, GTS, R, GT3 RS, two- or four-wheel drive—and the list goes on! All that stands between you and your dream combination is the contents of your wallet. The naturally aspirated engines are almost history, replaced in virtually all versions by a twin-turbo mill that pumps anywhere from 370 to 580 horsepower.
