- Recently Serviced By Mercedes - Obsidian Black Metallic Paint - Highly Collectible - Including Designo Classic Red Exclusive Leather (£5,055) - UK Supplied The SLS AMG combines exquisite retro styling with long smooth lines harking back to the Mercedes 300 SL of yesteryear. Under that beautiful nostalgic bodywork, the SLS is the first car that AMG have been given a clean sheet to do as they please, rather than giving a standard Mercedes the “AMG Treatment”, which always has its limitations. Being front-engined gives the SLS the advantage of having a reasonably sized boot, as well as being equipped with all the driver aids and comforts you would expect from a Mercedes-Benz. In Roadster format the SLS gives a visceral and connected open top driving experience unlike any other. With the sound of that naturally aspirated 6.2L V8 all the more audible with the roof down, this really is a car that needs to be experienced to be fully understood. Overall the SLS AMG Roadster blends retro-styling, German build quality and a uniquely brutish engine to produce a German drop-top muscle car like no other.
