The MERCEDES-BENZ S CLASS (2020-) S350L 4DR SALOON LWB 2.9D 286 DPFR SS EU6 AMG LINE PREMIUM PLUS EXECUTIVE 9G-T+ AUTO is a long-wheelbase luxury saloon, sitting at the top of the UK executive-car market. It prioritises rear-seat comfort, refinement and a prestigious presence over compact size or sporty practicality. As an S-Class, it is designed for buyers wanting a comfortable and well-equipped car for business or personal travel. mycarcheck.com records 422 look-ups covering 108 distinct VINs, a sample of UK interest. Checks show an average private-sale valuation of £74,300 and average recorded mileage of 44,000 miles. The average annual mileage is 21,000, while keeper history averages fewer than one previous keeper, at 0.66 previous keepers on average. That profile suits business travel and families wanting space and quiet long-distance comfort, rather than buyers seeking a small runabout. Its polished cabin, strong diesel performance and relaxed automatic drive make the S350L a refined alternative to the BMW 7 Series and Audi A8, although running costs remain premium overall.
