Mercedes-Benz continues to revitalize, and rename, its product line, with the latest example to be the transformation of the SLK retractable hardtop into the SLC. By adopting the classic SLC moniker, the brand is recognizing the roadster's C-Class pedigree while aiming to better align the models in its range. Some may recall that the SLC was a 2+2 coupe version of the SL from the late 1970s and early 1980s.
