The MERCEDES-BENZ S CLASS (2006-09) S600 4DR LIMOUSINE 5.5 AUTO is a large luxury saloon near the top of the UK used-car market. Built for comfort and presence rather than low-cost motoring, it offers a spacious, prestigious alternative to ordinary family cars and an indulgent executive-class choice for buyers. Mycarcheck.com has recorded 201 checks across 74 distinct VINs, a useful sample for this uncommon version. The average private-sale valuation is £10,100, while checked examples average 101,000 miles and about 3,000 miles annually. Owners averaged just over three previous keepers, suggesting buyers should review each car’s history and condition carefully. With its engine, automatic gearbox and comfortable cabin, the S600 suits executives, chauffeur use and drivers wanting long-distance travel. It stands out for comfort and presence against BMW 7 Series and Audi A8 rivals, but higher fuel and maintenance bills are part of ownership, so it suits budgeted luxury-car buyers.
