Mercedes-Benz’s SL-Class has always been a car for the discerning and powerful, or those that aspire to be so. It’s the brand’s true flagship (no matter what S-Class owners might tell you) and in its 69-year history, it’s had its ups and downs – though mostly ups. Playing favorites with SLs is splitting hairs, in other words, but they weren’t all created equal. From the Gullwing to today’s SL, here they are from least to most awesome.
