The MERCEDES-BENZ S CLASS (1999-06) S65 4DR LIMOUSINE 6.0 V12 AMG AUTO is a rare, full-size luxury saloon: a long, four-door flagship rather than an everyday hatchback or SUV. In the UK market it sits at the extravagant, high-performance end of executive motoring, combining chauffeur-friendly space with AMG muscle. mycarcheck.com has one recorded lookup for this exact model and one VIN, so its figures are a small snapshot, not a market-wide survey. That record shows an average private-sale valuation of £9,400, recorded mileage of 47,000 miles, and annual use of about 1,000 miles. It also reports four previous keepers, worth checking against the car’s paperwork and condition. Best suited to enthusiasts or buyers seeking comfort, presence and effortless pace, it is less practical for tight budgets or frequent fuel-conscious commuting. Its V12 AMG character makes it more distinctive than rivals such as the BMW 7 Series and Audi A8, but age, upkeep and condition matter.
