The MERCEDES-BENZ S CLASS (1999-06) S600 4DR LIMOUSINE AUTO LWB is a full-size luxury saloon, with a long-wheelbase body that prioritises rear-seat space and comfort. As a flagship Mercedes-Benz, it sat at the premium end of the UK market, alongside rivals such as the BMW 7 Series and Audi A8. Its limousine-style proportions give it a more imposing presence than an ordinary family car. mycarcheck.com records show 121 checks covering 35 distinct VINs, a useful snapshot of this uncommon, high-end model. The average private-sale valuation was £2,000, while average recorded mileage was 83,000 miles and typical annual use just 3,000 miles. Cars checked had around four previous keepers on average, so condition and history deserve close attention. It suits buyers typically seeking comfort on long journeys or executive travel, rather than first-time drivers or tight budgets. Refinement and equipment stand out, but upkeep can be costly and fuel economy modest.
