The AUDI A6 (2004-09) 5DR AVANT 2.4 V6 S LINE MTRON AUTO is a premium five-door estate, offering more load space than the A6 saloon while retaining a comfortable feel. In the UK used-car market, it sits above mainstream family estates, appealing to buyers wanting understated executive style and practicality. mycarcheck.com has recorded 17 look-ups covering seven distinct VINs, a limited sample rather than a market-wide picture. The checks show an average private-sale valuation of £1,500, average recorded mileage of 118,000 miles and four previous keepers; average annual mileage is 6,000 miles. Treat these figures as useful context, not a price guarantee. The spacious boot and relaxed automatic suit family trips, commuting and bulky loads. V6 character and S line styling give the A6 more presence than mainstream estates, while BMW 5 Series Touring and Mercedes-Benz E-Class rivals offer similar executive appeal. Check condition and service history carefully for practical executive-car buyers.
