Buyer's Guide & Data from our Checks
The MERCEDES-BENZ S CLASS (2017-20) S350L 4DR SALOON 2.9D DPFR SS 286 EU6 AMG LINE EXECUTIVE 9G-T+ AUTO is a long-wheelbase luxury saloon, sitting near the top of the UK executive-car market. It prioritises rear-seat comfort, refinement and a prestigious presence over compact size or low-cost motoring.
Its spacious cabin and smooth diesel power make it well suited to business travel, motorway journeys and owners who regularly carry passengers; it can also serve as a comfortable family car, though its size and running costs may not suit everyone. AMG Line Executive trim adds a sporty look and generous equipment, while the automatic gearbox is designed for relaxed progress. Against rivals such as the BMW 7 Series and Audi A8, the S-Class is especially known for comfort and a polished, quiet ride.
