The MERCEDES-BENZ S CLASS (2020-) S400L 4MATIC 4DR SALOON LWB 2.9D 330 DPFR SS EU6 AMG LINE PREMIUM 9G-T+ AUTO is a long-wheelbase, four-door luxury saloon in the UK’s top executive-car class. It pairs a spacious cabin and AMG Line styling with diesel power, four-wheel drive and automatic transmission, offering an alternative to premium SUVs. This S-Class suits business users, chauffeur duties and buyers seeking generous rear-seat room and quiet, long-distance comfort. The 4MATIC system adds confidence in poor conditions, while its long body gives passengers more space than a standard saloon. Against rivals such as the BMW 7 Series and Audi A8, it is known for a luxurious, technology-rich feel; AMG Line adds sportier styling without changing its comfort-first character. mycarcheck.com recorded nine checks across four VINs, a modest sample; figures should be treated as indicative. Average private-sale value was £56,900, mileage 49,000, annual use 12,000 miles and previous keepers 1.4.
