A New York teen taking a test drive of a family friend's Lamborghini has died after crashing the high-powered sports car into a guardrail.

Police say 18-year-old Samuel Shepard was taking the car for a spin on a county road in Mount Sinai on Long Island early Friday when he lost control. The car's owner, Michael Power, was a passenger in the car and was treated for nonlife-threatening injuries.

Det. Sgt. Michael Fitzharris tells Newsday (http://nwsdy.li/1vUWXaU) that excessive speed is believed to be a factor in the crash.

Of the test drive, Fitzharris says, "I think it was probably just a once-in-a-lifetime opportunity for the kid, and this man chose to give him this opportunity."

Shepard's father, Gene, tells the newspaper that Lamborghinis were his son's favorite car.
