The AUDI A6 (2004-09) 5DR AVANT 4.2 FSI QUATTRO SE TIP AUTO is a premium five-door estate, pairing executive comfort with useful luggage space. In the UK used market it sits above mainstream family estates, appealing to buyers wanting room for passengers and holidays with extra power and refinement. It is best suited to experienced drivers, couples or families who value a spacious, comfortable long-distance car and can accept higher running costs; the large petrol engine is unlikely to be a fuel-saving choice. Mycarcheck.com records 84 look-ups across 17 different VINs. Those checks show average recorded mileage of 150,000 miles, around 3,000 miles a year, and about five previous keepers. Checks give an average private-sale valuation of £1,200, not a guaranteed price. Quattro all-wheel drive and automatic transmission lend this A6 Avant confident, relaxed manners, making it a distinctive alternative to BMW 5 Series and Mercedes E-Class estates of its era.
