The MERCEDES-BENZ S CLASS (1999-06) S500 4DR LIMOUSINE 5.0 AUTO LWB 7SP is a full-size luxury saloon, rather than a family hatchback or SUV. Its long-wheelbase body gives rear passengers extra room, while the smooth automatic V8 and generous equipment place it among the most prestigious used cars of its era in the UK. mycarcheck.com has recorded 75 checks covering 40 different VINs, a useful sample for this specialist model. Checks show an average private-sale valuation of £2,400 and average recorded mileage of 121,000 miles. Average annual mileage is just 3,000, while cars have had around five previous keepers, so condition, maintenance history and use deserve close attention; values and individual cars can vary. This S500 suits buyers wanting comfortable travel or chauffeur-style rear space, not cheap motoring. It offers dignified refinement against BMW 7 Series and Audi A8 rivals, but fuel and upkeep can be costly; inspect its history.
