18. Mercedes W123 AMG
The W123 series of Mercedes sedan is well-known around the world as one of the most durable and elegant executive sedans of the period. Since it was a Mercedes product, AMG had it in their workshop and the result was the Mercedes W123 280 AMG.
The 2.8-liter twin-cam engine was thoroughly upgraded as well as the suspension and aerodynamics. And the stately-looking sedan now delivered 210 HP and exciting performance. Buyers could get the car with or without the graphics package, which was late ’70s looking.
