From 1967 to 1971, Mercedes produced around 23,885 of the W113, 280SL “Pagoda,” a model nicknamed for its slightly concave removable top. It boasted the last update to the SOHC M180 inline-six by Mercedes-Benz and buyers could choose an optional limited-slip differential. Heavier than its predecessors, the 230SL and 250SL, the 280 SL is popular amongst car enthusiasts and has become known as one of the most reliable and sturdy Mercedes-Benz models ever produced.
