Updating Mercedes' $200,000 supercar may seem like a thankless task. Nonetheless Vilner worked its magic on the SLS AMG by adding yet more luxury to the already-opulent coupe on the instructions of a particularly discerning customer. The Bulgarian interior specialist outfitted the cabin with a leather and Alcantara-wrapped steering wheel, and covered the storage pocket between the seats in leather. Vilner also retrimmed the trunk with two-tone Alcantara upholstery and embroidered AMG badge.
