The MERCEDES-BENZ S CLASS (1999-06) S55 AMG 4DR LIMOUSINE 5.5 AUTO LWB REV02 is a large, long-wheelbase luxury saloon, sitting near the top of the used-car market rather than serving as an everyday budget runabout. Its extended cabin and powerful AMG character combine executive comfort with a more spirited feel than a standard S-Class. It is best suited to buyers wanting a spacious car for business travel, special occasions or relaxed long-distance journeys, and who can budget for upkeep appropriate to an older flagship. In mycarcheck.com data, 85 checks covered 33 distinct VINs; average recorded mileage was 109,000 miles, with around 1,000 miles driven annually. Checks show about five previous keepers on average and a £2,500 average private-sale valuation. Against rivals such as the BMW 7 Series and Jaguar XJ, the S55 AMG stands out for its imposing presence, plush ride and performance; buy carefully on condition, not badge alone.
