The AUDI A6 (2004-09) 5DR AVANT 3.2 FSI QUATTRO SE is a premium estate car, a practical alternative to executive saloons in the UK used-car market. Its roof and roomy load area suit family duties, holidays and bulky shopping, while retaining the comfort expected of an executive car. mycarcheck.com checks recorded 15 look-ups across seven distinct VINs, a modest sample rather than a broad market picture. The data shows an average private-sale valuation of £1,400, average recorded mileage of 171,000 miles, and annual mileage of 5,000 miles. Cars had an average of around three to four previous keepers. The 3.2-litre petrol engine and Quattro four-wheel drive give this A6 an assured feel, especially in poor weather, though fuel costs may exceed those of smaller-engined rivals. It suits drivers wanting comfort, space and confident all-weather travel more than the lowest running costs, competing with BMW 5 Series Touring and Mercedes E-Class estates.
