The AUDI A6 (2004-09) 5DR AVANT 2.8 FSI QUATTRO S LINE TIP AUTO is a premium estate, offering more load space than the A6 saloon while retaining an executive-car feel. In the UK used market, it suits buyers wanting a spacious, comfortable alternative to an SUV, rather than a family hatchback. Its 2.8-litre petrol engine, automatic gearbox and Quattro four-wheel drive are aimed at relaxed, confident travelling, while S line trim adds a sportier appearance. The Avant’s roomy cabin and useful boot make it well suited to families, holiday trips and drivers who carry items; it is less suited to tight city parking or economy-focused motoring. Against BMW 5 Series Touring and Mercedes-Benz E-Class estates, it stands out for sure-footed grip and a composed, premium feel. Mycarcheck’s two look-ups cover one VIN, so figures are indicative: 139,000 average mileage, 8,000 annual miles, two keepers and £1,500 average private-sale valuation in these checks.
