The AUDI A6 (1997-04) 5DR AVANT 2.4 V6 170 QUATTRO is a large, premium five-door estate, known as the Avant, rather than an SUV or ordinary family hatchback. It sits in the UK executive-car market, offering generous load space and a more refined feel than mainstream estates of its era. Its 2.4-litre petrol V6 and Quattro four-wheel drive give smooth, confident progress, while the roomy cabin and useful boot suit family trips, commuting and carrying bulky gear. Compared with rivals such as the BMW 5 Series Touring and Mercedes-Benz E-Class estate, it is a practical choice with reassuring all-weather traction. mycarcheck.com has one lookup for this A6, so figures are only a snapshot: private-sale value £400, mileage 121,000, annual use 2,000 miles and seven previous keepers. Check condition, service history and running costs carefully; this luxury estate may suit a considered buyer, though upkeep can outweigh a low purchase price.
