4. Mercedes-Benz E55 AMG (W210)

The Mercedes-Benz E55 AMG (W210) is the definition of understated performance. On the outside, it’s an elegant executive sedan, but a hand-built 5.4L V8 lurks beneath, delivering blistering acceleration and an impressive top speed.
With its refined appearance and plush interior, this AMG is the ultimate sleeper. Road & Track frequently ranks it alongside classic muscle cars—often with the Mercedes emerging victorious in real-world tests.
