The MERCEDES-BENZ S CLASS COUPE & CABRIOLET (2017-21) AMG S63 2DR CABRIOLET 4.0 V8 BITURBO 612 SS EU6 S SPDS MCT AUTO9 is a high-performance, four-seat luxury convertible and a UK-market flagship. It pairs open-air appeal with limousine-style comfort, while its AMG character sets it apart from ordinary grand tourers. Mycarcheck.com recorded 42 look-ups covering 25 distinct cars, a snapshot rather than a huge sample. Those checks show an average private-sale valuation of £77,700, around 25,000 miles recorded and roughly 5,000 miles driven annually. The average keeper count is just over one, suggesting many examples have had limited ownership changes. This S63 suits buyers seeking a weekend car or long-distance cruiser, not an economical daily runabout. Its powerful V8, refined cabin and folding roof blend speed, luxury and open-air motoring. Against the Bentley Continental GTC and BMW 8 Series Convertible, it stands out for effortless pace and distinctive AMG presence.
