There are a number of Class types produced by Mercedes-Benz Benz, and all of them designate different types of vehicles that have been introduced into the lineup. The SL-Class are grand tourer sports cars that have been in production since 1954. "SL" stands for "super-leicht" in German, or "Super Light" in English. Many cars have been introduced in this lineup. The first 300 SL was introduced in 1954 as a coupe, and there have been many models that have come after. These include the SL 320, which replaced the 300 SL in the United States in 1995. The car featured a 3.2 liter I6 engine. If you're driving a SL 320, you want to be sure you're investing in OEM parts and accessories that will fit your specific model. We sell them for SL 320 models here on our Official Mercedes-Benz Parts Store.
