The AUDI A6 (2004-09) 4DR SALOON 2.0T FSI 170 SE MTRON AUTO is a large, four-door executive saloon, sitting above mainstream family cars in the UK used-car market. It pairs a roomy cabin and boot with a petrol engine and automatic gearbox, making it a more comfort-focused choice than a compact hatchback. Mycarcheck.com records 66 look-ups covering 48 distinct VINs, a useful snapshot rather than a full picture of every A6. Across those checks, average private-sale valuation was £1,300, recorded mileage averaged 116,000, and annual mileage 5,000; cars had about 3.5 previous keepers on average. The A6 suits commuters and families seeking space and comfort on longer journeys; its automatic gearbox also helps in town. SE trim feels well equipped, while the turbocharged petrol engine provides brisk response. Compared with the BMW 5 Series and Mercedes-Benz E-Class, it is understated and refined. Check service history and condition carefully before buying.
