The MERCEDES-BENZ S CLASS (2017-20) S450L 4DR SALOON LWB 3.0 SS 389 EU6 AMG LINE EXECUTIVE PREMIUM PLUS 9G-T+ AUTO is a spacious flagship luxury saloon, sitting above family cars in the UK market. Its long-wheelbase body prioritises rear-seat room, while AMG Line styling gives this executive Mercedes a sharper, more purposeful look. Mycarcheck.com records 29 checks covering 11 distinct VINs: a snapshot, though not a huge sample. Recorded cars averaged £35,300 in private-sale value and 58,000 miles, with 17,000 miles a year and around 1.2 previous keepers. These figures suggest many examples have been used, so check mileage, history and condition against each individual car. Best suited to buyers wanting quiet, comfortable long-distance travel, business users and families needing space, the S450L is less practical to park or run than a mainstream saloon. Its premium cabin, smooth automatic driving and equipment make it an alternative to the BMW 7 Series and Audi A8, and a standout choice for relaxed, prestigious journeys.
