The MERCEDES-BENZ S CLASS (1999-06) S55 AMG 4DR LIMOUSINE 5.5 AUTO LWB is a large, long-wheelbase luxury saloon with a powerful petrol engine and automatic gearbox. In the UK, it occupies the premium executive-car end of the market, offering more space and presence than an ordinary family car. Mycarcheck.com has recorded 28 look-ups covering 11 different VINs, so the figures offer a useful snapshot rather than a huge sample. The average private-sale valuation is £1,600, with average recorded mileage of 128,000 miles and annual use of 8,000 miles. Checks show nearly six previous keepers on average, making careful history and condition checks especially worthwhile. It is best suited to enthusiasts or drivers wanting a car for journeys, not low-cost motoring. The S55 AMG adds a sportier edge while retaining limousine-like comfort, and stands apart from rivals including the BMW 7 Series through its blend of prestige, performance and rear seating.
