The 2013 Lamborghini Aventador Roadster remains a car that grabs everyone's attention. And at $445,000, it should. The Roadster adds $65,000 over the coupe, but the openness adds a more visceral experience. And it's not like a Lamborghini buyer will miss the 65k, if we're honest. With 700 hp deriving from its V-12 engine, it'll sprint to 60 mph in 2.9 seconds. This year marked Lamborghini's 50th birthday.
