The AUDI A6 (2004-09) 5DR AVANT 3.2 FSI SE MTRON AUTO is a large, premium five-door estate, offering more luggage space than the A6 saloon while retaining executive-car comfort. In the UK used market it sits among family and business estates, rather than affordable small runabouts. Its 3.2-litre petrol engine and automatic gearbox make it a relaxed, smooth choice for longer journeys, with a spacious cabin suited to families, commuters and drivers who regularly carry bulky loads. This powerful petrol version is less focused on fuel economy than smaller or diesel A6s, so running costs deserve consideration. Compared with estate rivals such as the BMW 5 Series Touring and Mercedes-Benz E-Class Estate, it is known for understated styling, comfort and a solid, refined feel. mycarcheck.com records five look-ups across two VINs, so figures are indicative: average mileage is 169,000, annual use 8,000 miles, keepers 2.8 and average private-sale value £1,200.
