The Mercedes-Benz R107 and C107 were produced from 1971 through 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, etc. up to the 560 SL.
The R107 replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989. The SLC replaced the W111 Coupé in 1971 and was replaced by the C126 S-class coupe in 1981.

From September 1985 the 280 SL was replaced by a new 300 SL, and the 380 SL by a 420 SL; the 500 SL continued and a 560 SL was introduced for certain extra-European markets, most notably the USA. Also in 1985, the Bosch KE Jetronic was fitted. The KE Jetronic system varied from the earlier, all mechanical system by the introduction o
