Today, Anthony Reynolds, 18, pleaded guilty to carjacking a Porsche in Newark earlier this year. And he might have gotten away with it—if he knew how to drive stick.

According to the Star-Ledger, Reynolds admitted to threatening the driver of a 2008 Porsche 911 with a .38-caliber handgun and ordering him out: "The driver of the Porsche ran from the car and flagged a passing police officer, telling him he had been carjacked at gunpoint. The driver of the first stolen car, a 2006 3-series silver BMW, fled east on Bloomfield Avenue. But Reynolds, who couldn’t drive a manual transmission, stalled the 480-horsepower, six-speed engine... With police approaching, and still unable to get the Porsche running, Reynolds bolted on foot, said [U.S. Attorney Paul] Fishman. After a brief chase, he was caught."

Reynolds, who was charged with theft of a motor vehicle by force, violence and intimidation, now faces up to 15 years in prison and a fine of up to $250,000.
