The AUDI A6 (2014-19) 4DR SALOON QUATTRO 2.0 TFSI SS 252 EU6 S LINE STRON AUTO7 is a premium four-door executive saloon, sitting above mainstream family cars and competing with the BMW 5 Series and Mercedes-Benz E-Class. Its smart, understated design suits business travel as well as everyday use. Quattro four-wheel drive gives reassuring grip, while the 252-horsepower petrol engine and automatic gearbox make motorway journeys smooth and confident. S line trim adds a sportier look, but the A6 remains a comfortable, spacious choice for professionals, couples or families needing room for passengers and luggage. It is less suited to buyers prioritising low running costs than a smaller car. mycarcheck.com recorded 20 checks across eight distinct VINs, a useful snapshot rather than a large sample. These showed an average private-sale value of £16,700, 50,000 miles, 3,000 miles driven yearly and 1.35 previous keepers, suggesting lightly used examples in this data overall.
