The MERCEDES-BENZ S CLASS (2017-20) S350 4DR SALOON 2.9D DPFR SS 286 EU6 AMG LINE PREMIUM PLUS 9G-T+ AUTO is a large, four-door luxury saloon, sitting at the top end of the UK executive-car market. It is designed around quiet comfort, generous space and a polished, confident presence, rather than compact city driving. AMG Line styling gives this S-Class a sportier look while retaining its traditional limousine character. It suits business users, frequent motorway commuters and families wanting a refined long-distance car, with room for passengers and luggage. The 2.9-litre diesel and smooth automatic transmission make relaxed, effortless progress, and should appeal to drivers covering regular miles. Against the BMW 7 Series and Audi A8, the S-Class is especially known for comfort and a sumptuous cabin. mycarcheck.com recorded 278 checks across 85 distinct cars, a sample worth noting.
