The AUDI A6 (2004-09) 5DR AVANT 3.2 FSI QUATTRO S LINE is a premium five-door estate, rather than a hatchback or SUV. It sits in the executive-car part of the UK used market, offering generous passenger space and a practical load area alongside a smart, upmarket feel. Its S line trim adds a sportier look, while quattro four-wheel drive is designed to provide reassuring grip in changing conditions. Mycarcheck.com recorded 18 look-ups for this model, covering four distinct VINs, so the figures offer a snapshot rather than a broad market census. The average private-sale valuation was £1,200, with average recorded mileage of 124,000 miles and annual mileage of 4,000. Cars checked had about 4.4 previous keepers on average. Best for families and long-distance drivers, it pairs estate practicality with all-weather confidence; against BMW and Mercedes estates, its sporty feel stands out, though fuel costs deserve consideration.
