The AUDI A6 (2004-09) 5DR AVANT 2.7 TDI SE is a large, five-door estate, offering more luggage space than the A6 saloon while retaining an executive-car feel. In the UK used-car market, it sits above estates, appealing to buyers wanting comfort, room and a badge without choosing an SUV. mycarcheck.com records 157 checks across 87 different VINs, a snapshot of this older model. Checked cars averaged 168,000 miles, around 11,000 miles annually and 4.35 previous keepers; average private-sale valuation was £1,000. These figures are not a guide to an individual car’s condition, so check its history and maintenance carefully. The 2.7-litre diesel makes the Avant suited to commuting and family holidays, with an easy, refined drive. Its roomy boot carries family luggage, making it a practical alternative to an SUV. Against BMW and Mercedes estates, this A6 is understated, comfortable and well suited to long-distance travel for motorway users.
