Buyer's Guide & Data from our Checks

The AUDI A6 (2004-09) 4DR SALOON 4.2 FSI QUATTRO S LINE TIP AUTO is a large, premium four-door saloon, designed for buyers wanting more space and comfort than a family hatchback. In the UK used-car market, it competes with executive rivals such as the BMW 5 Series and Mercedes-Benz E-Class.

Built for confident long-distance travel, this A6 suits professionals, couples and families seeking a refined everyday car with room for passengers and luggage. Its 4.2-litre petrol engine, automatic gearbox and Quattro four-wheel drive give it a distinctive blend of strong performance, smooth cruising and added grip; S line styling brings a sportier look. Running costs and fuel use are likely higher than smaller-engined A6 versions, so it may suit buyers prioritising pace and comfort over economy.
