The Porsche that James Dean died in went on to kill and severely injure multiple people.

Obviously, whether it is haunted or not is up to speculation and personal belief. James Dean was a very popular American film actor known most notably for the film Rebel Without a Cause who died in a car crash on September 30, 1955. The car he was driving was a rare Silver Porsche Spyder, which he had nicknamed “The Little Bastard.” 

As devastating as Dean’s death was, the really strange things are what happened afterward. Some time after the crash, a car customizer named George Barris bought the wreck of the Porsche for $2,500. While moving it into his garage, it slipped and fell onto one of the mechanics moving it, resulting in two broken legs. 

During a race in 1956, two men were racing cars that had parts from Little Bastard. The first man, Troy McHenry, died when his car went out of control and hit a tree. The other man, William Eschrid, had his car flip over and was severely injured. He later said the car suddenly locked up when he was trying to turn. 

One kid tried to steal Little Bastard’s steering wheel after the race, but fell and gashed his arm. Barris sold two of Little Bastard’s tires to a man, who nearly died a few days later when they both blew out simultaneously. 

Barris loaned the car to the California Highway Patrol, and within days the garage housing it burned to the ground, along with all other cars except Little Bastard. The car was eventually put on exhibit, where it fell and broke a teenager’s hip.

A man hauling it on a flatbed truck died when he lost control of his vehicle and Little Bastard fell on him. The remains of the car vanished in 1960, presumably to resurface in the 1970's as the Ford Pinto.
