Mercedes-Benz and AMG have always been quite chummy, as shown by this AMG 280 based on a W123 from the early 80s. The bodykit turns this quiet sedan into a sporty looking car but it's under the hood that the shape of the beast becomes clear. Its 4-speed propulsion can handle 212 horsepower, and with a top speed of 209 km/h, it is one of the most efficient sedans to monopolize the left lane on the unbridled motorways of Germany.
