The AUDI A8 (2013-18) S8 4DR SALOON QUATTRO 4.0 TFSI SS 605 EU6 PLUS TIP AUTO8 is a large luxury performance saloon: a high-end executive car rather than an everyday hatchback or SUV. It combines discreet four-door comfort with rapid, all-weather performance, placing it among the most powerful versions of Audi’s flagship A8 range. mycarcheck.com recorded 264 look-ups covering 65 distinct VINs, giving useful market context. The cars checked averaged 51,000 miles and 6,000 miles a year, with 2.25 previous keepers; the average private-sale valuation was £28,800. These figures are guide points from checks, not a guarantee of condition or current asking price. Best suited to drivers wanting refined long-distance travel, it can double as a family car, though running costs will exceed those of mainstream saloons. Against the BMW 7 Series and Mercedes-Benz S-Class, this used Audi S8 stands out for pairing limousine-like comfort with sports-car pace and surefooted all-weather grip.
