The Exterior Carbon-Fibre package in matt finish is exclusive to the SL 65 AMG '45th ANNIVERSARY'. The cross strut in the front apron, the exterior mirrors and the spoiler lip are produced in genuine carbon fibre wîth a satin finish. The AMG 6.0-litre V12 biturbo engine features the same look: the high-quality engine cover consists of matt carbon fibre and aluminium. A defining stylistic element is the upholstery in designo Exclusive STYLE leather in titanium grey pearl/ginger beige. The distinctive upholstery featuring the AMG-specific V12 layout wîth a diamond pattern adorns both the electrically adjustable AMG sports seats and the door centre panels. Embossed AMG emblems on the seat backrests exude the same class as the designo nappa leather roof lining in ginger beige featuring special stitching details in AMG V12 diamond pattern. The AMG Performance §teering wheel sports an AMG logo in its bottom bezel and offers a two-tone rim in titanium grey/ginger beige. The AMG trim elements are also finished in matt carbon fibre to match the matt finish of the Exterior Carbon-Fibre package. A badge on the ashtray cover bearing the logo '45th ANNIVERSARY – 1 OF 45' alludes to the 45th birthday of the AMG high-performance brand and highlights the exclusive character of this very special SL 65 AMG.
