The MERCEDES-BENZ S CLASS (2017-20) AMG S63L 4DR SALOON 4.0 V8 SS 612 EU6 SPDS MCT AUTO9 is a large, long-wheelbase luxury saloon at the top end of the UK executive-car market. It combines limousine-like space and comfort with striking performance, making it far removed from an ordinary family saloon. Mycarcheck.com records 125 checks across 27 different VINs, a useful sample for this rare, expensive model. The average private-sale valuation was £59,100; average recorded mileage was 42,000 miles, with annual use around 9,000 miles. Cars checked had about 1.5 previous keepers on average, suggesting relatively few owners. It suits buyers seeking long-distance comfort, a prestigious business car or a spacious, fast saloon. Its size and running costs make it less practical for tight budgets or city parking. Against the BMW 7 Series and Audi A8, the S63L pairs sumptuous comfort with more overt performance. A quiet cabin and rapid acceleration are key attractions. Check service history and condition carefully before making your final purchase decision.
