A late-night Lamborghini “test drive” turned fatal this weekend, when a Mount Sinai, New York teenager smashed the high-powered luxury vehicle into a guardrail at high speeds.

Police say Sam Shepard, a recent high school graduate and aspiring Army Ranger, was driving north at 2:25 a.m. when he lost control of a 2010 Lamborghini and crashed into a guardrail near Route 25A, shutting down County Road 83 for almost nine hours, Newsday reports.

The car belonged to longtime family friend, Michael Power, 49, who was also a passenger at the time of the accident. He was taken to the hospital and treated for non life-threatening injuries.

According to news reports, detectives believe Power met Sam at a parking lot near his home, where they discussed taking a test drive in the Lamborghini.

“I think it was probably just a once-in-a-lifetime opportunity for the kid, and this man chose to give him this opportunity,” Det. Sgt. Michael Fitzharris of the Sixth Precinct told Newsday.

He believes the two were returning to the parking lot when the crash occurred.

Sam’s father, Gene Shepard, owns an auto body shop and confirmed that the Lamborghini was his son’s favorite car.

“Since he’s a kid, he’s been around cars,” Shepard told Newsday. “He was a very talented kid with his hands. He always helped me at the shop. … He used to see his dad was working hard, and he’d pick up tools and start helping.”
