The MERCEDES-BENZ S CLASS COUPE & CABRIOLET (2017-21) S560 2DR COUPE 4.0 V8 BITURBO 469 GPF SS EU6 AMG LINE PREMIUM 9G-T AUTO is a large, two-door luxury grand tourer, sitting near the top of the UK coupe market. It pairs dramatic styling and a hushed, richly equipped cabin with effortless V8 performance, rather than the practicality or low running costs of a family hatchback. mycarcheck.com records 225 checks across 63 distinct S560s: a useful snapshot, though not a huge sample. Average private-sale valuation is £61,500, with 26,000 miles recorded and annual mileage around 6,000. The average keeper count is 1.23, suggesting relatively lightly used examples; check each car’s history individually. Best for couples or drivers wanting a refined long-distance car, it delivers comfort, prestige and strong acceleration, but is less practical for rear-seat use or tight budgets. AMG Line Premium adds sporty styling and equipment. Against the BMW 8 Series, the S-Class Coupe stands out for limousine-like comfort and polished luxury; fuel and maintenance costs also reflect its high-end status.
