The Mercedes-Benz R107 and C107 are automobiles which were produced by Mercedes-Benz 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, 350SL, 420SL, 450SL, 500SL and 560 SL.

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, notably the USA, Australia and Japan. The KE Jetronic system varied from the earlier, all mechanical system by the introduction of a more modern engine management "computer", which controlled idle speed, fuel rate, and air/fuel mixture.The final car of the 18 years running 107 series was a 500 SL painted Signal red, built on August 4, 1989; it currently resides in the Mercedes-Benz museum in Stuttgart, Germany. From 1974, the front and rear bumpers were dramatically lengthened, by 8 inches (203 mm) on each end, to comply with the U. National Highway Traffic Safety Administration regulations, that mandated no damage at an impact of 5-mile-per-hour (8 km/h).The R107/C107 for the North American market sported four round low-output sealed beam headlights, due to unique U.

With the exception of the SL65 AMG Black Series, the SLC remains the only fixed roof Mercedes-Benz coupe based on a roadster rather than a sedan.Following the discontinuation of the SLC in September 1981, the 107 series continued initially as the 280, 380 and 500 SL.The R107/SL was a 2-seat car with a detachable roof.It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.The more you read, the better we get at understanding your interests, refining the selection of stories delivered to your screen so they are relevant to you.
