Since its introduction in 2012, the Lamborghini Aventador LP 700-4 has been one of the world's most desirable high-performance driving machines. The thrilling design is matched only by the car's otherworldly performance. Starting with a 691-horsepower V12 engine and all-wheel drive, Lamborghini wraps the engine and passenger compartment in aluminum and carbon-fiber body work that's straight out of a science fiction fantasy. But it's not just for show, as the huge door vents, and numerous slots and slats all work to keep the car's engine fed with air, and to keep it on the ground as it rockets from a standstill to 60 mph in less than three seconds, all on its way to an astonishing 217 mph top speed. It's $400,000 that's very well spent.
