The MERCEDES-BENZ S CLASS (1999-06) S430 4DR LIMOUSINE 4.3 AUTO LWB 7SP is a full-size, long-wheelbase luxury saloon, aimed at buyers wanting a spacious, comfortable alternative to an executive hatchback or SUV. In the UK market it sat near the top of the range, competing with the BMW 7 Series, Audi A8 and Jaguar XJ. With its V8 petrol engine, automatic gearbox and extended rear cabin, the S430 is best suited to relaxed long-distance travel, chauffeur duties or owners who value quiet comfort and room for passengers. It offers a more formal, substantial feel than many rivals, though running costs and fuel use are likely to be higher than in smaller cars. mycarcheck.com records 17 look-ups across three VINs, so its sample is modest. The average checked car showed 103,000 miles, around 2,000 miles a year, nearly seven previous keepers and a £1,200 private-sale estimate; condition and history matter greatly.
