- Obsidian Black Metallic Paint - High Spec Long Wheel Base Example (130mm Extra Rear Legroom) - Including Executive Equipment Line (£3,510) & Rear Seat Entertainment (£2,450) - UK Supplied The S-Class has long been considered the flagship model for Mercedes-Benz showcasing the latest technology and features the German giant has to offer. Whilst the S-Class Coupe and Cabriolet have very much catered for those that like to get behind the wheel, the Saloon variant is for those that like to be driven, especially in this long wheel base variation. The stretched wheel base, denoted by the "L" seen at the end of the cars name, adds 130mm of rear leg room to the already palatial cabin space of the S-Class. High levels of refinement ensure this is a luxurious and comfortable cruiser when you want it to be, however, it is equally at home behaving as a German muscle car with bundles of power and torque contributing to what is a scintillating soundtrack.
