A security guard watches as Ford Motor Company Executive Chairman Bill Ford stands on top of the observation deck at the Empire State Building with the new 2015 Mustang convertible in honor of 50 years of the Ford Mustang on April 16, 2014 in New York City. In 1965 a prototype Ford Mustang convertible made its way to the top of the observation deck. This time the iconic American car had to be brought up in parts and assembled on location. The Mustang will be on display for two days in celebration of the kick-off of the 2014 New York International Auto Show. (Photo by Spencer Platt/Getty Images)
