Buyer's Guide & Data from our Checks
The MERCEDES-BENZ S CLASS (2017-20) S450L 4DR SALOON LWB 3.0 GPF SS 389 EU6 GRAND EDITION 9G-T+ AUTO is a long-wheelbase luxury saloon, sitting at the top end of the UK executive-car market. It prioritises quiet comfort, space and prestige over compact dimensions or low running costs, with a formal presence.
Its extended rear cabin makes it especially suited to chauffeur work, business travel and owners who carry passengers; it can also serve as a comfortable long-distance car. The S450L blends a smooth petrol-powered drive with high-end refinement and equipment, competing with top versions of the BMW 7 Series and Audi A8.
