The AUDI A6 SALOON (2019-25) S6 4DR SALOON QUATTRO 3.0 TDI V6 344 DPFR SS EU6 TIP AUTO8 is a premium, four-door executive saloon: spacious and polished rather than a small city car or SUV. Its strong diesel engine, automatic gearbox and four-wheel drive give it brisk, confident all-weather performance. On mycarcheck.com, the available picture is based on just four checks covering four different VINs, so figures are indicative, not a broad market measure. Those records show an average private-sale valuation of £33,900 and average recorded mileage of 26,000 miles. The average previous-keeper figure was 0.25, an unusually low result from this small sample. Suited to commuters, business users and families, it offers motorway comfort, space and a livelier drive than a standard A6. The S6 blends performance with diesel range and usability, rivaling BMW 5 Series and Mercedes-Benz E-Class models. Check condition, service history and running costs before buying.
