Nicknamed the “Wolf in Sheep’s Clothing,” the 500E looked like any other W124 sedan—but appearances deceived. Beneath the hood sat a 5.0L V8 with 322 hp, capable of sports-car levels of performance. Hand-assembled in collaboration with Porsche at Zuffenhausen, each car took 18 days to build, making it one of the most discreet yet exclusive sports sedans of the 1990s.
