The MERCEDES-BENZ S CLASS (2020-) S400L 4MATIC 4DR SALOON LWB 2.9D 330 DPFR SS EU6 AMG LINE PREMIUM PLUS EXECUTIVE 9G-T+ AUTO is a spacious, high-end diesel saloon, sitting at the top of Mercedes-Benz’s range. Its long-wheelbase body prioritises rear-seat room and comfort, while AMG Line styling adds a sportier look. It competes with the BMW 7 Series and Audi A8 rather than ordinary family cars. On mycarcheck.com, 196 checks covered 21 distinct VINs, offering a useful snapshot, though not a full measure of every car. The average recorded private-sale value was £80,000, with average mileage of 37,000 and annual use of 16,000 miles. Checks showed 0.3 previous keepers on average. This S400L suits buyers wanting long-distance travel, chauffeur-driven space or comfort; it is less suited to tight budgets or city parking. Four-wheel drive and an automatic gearbox support relaxed journeys, while the diesel engine makes it practical for motorway use. Its blend of refinement, space and prestige is its appeal.
