The AUDI A8 (2018-22) 50 4DR SALOON QUATTRO LWB 3.0 TDI V6 286 DPFR SS EU6 S LINE COMFORT SOUND PACK TIP AUTO8 is a large, four-door luxury saloon, sitting near the top of Audi’s range. Its long-wheelbase layout prioritises spacious rear seating, while quattro all-wheel drive and a smooth automatic gearbox add reassuring refinement. Across 24 mycarcheck.com look-ups covering eight distinct cars, the average private-sale valuation was £36,300. Recorded examples averaged 39,000 miles and around 12,000 miles annually, with roughly one or two previous keepers. These figures offer a useful snapshot, not a guaranteed price or a complete picture of every A8. It suits executives, motorway travellers and families seeking long-distance transport rather than a city car. Against BMW 7 Series and Mercedes-Benz S-Class rivals, the A8 is known for understated styling, a calm ride and technology; this S line version adds a sportier feel while retaining comfort.
