The RedArt Edition boasts red accents inside and out, while the SL Designo Edition pairs a blue exterior with a 'porcelain' leather interior.
As its name implies, the RedArt packages feature red exterior highlights and matching interior accents. Red customizations include the front splitter, radiator grille elements, wing fins and diffuser trim, while the twin-spoke alloy wheels are painted in high-sheen tremolite metallic.
For the SLC 43 AMG variant, the RedArt Edition boasts unique five-spoke wheels, AMG front and rear aprons and sports suspension, along with a few interior tweaks.
The SL Designo takes a different approach, distinguished by its brilliant metallic blue exterior and 10-spoke AMG wheels. Its interior features a lighter color scheme with porcelain/black napa leather and piano lacquer champagne leather.
