The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker, after the G-Class. They were sold under the SL (R107) and SLC (C107) model names as the 280 SL, 280 SLC, 300 SL, 350SL, 350SLC, 380SL, 380SLC, 420SL, 450SL, 450SLC, 450SLC 5.0, 500SL, 500SLC and 560 SL.

The R107/SL was a two-seat car with a detachable roof. It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.

From 1993, the 124 series was officially marketed as the E-Class. The W 124 followed the 123 series from 1984 and was succeeded by the W 210 E-Class (saloons, estates, rolling chassis) after 1995, and the C 208 CLK-Class (coupés, and cabriolets) in 1997.

In North America, the W124 was launched in early November 1985 as a 1986 model and marketed through the 1995 model year. Series production began at the beginning of November 1984, with press presentation on Monday, 26 November 1984 in Seville, Spain, and customer deliveries and European market launch starting in January 1985.
