The AUDI A6 (1997-04) 4DR SALOON 2.7T 250 QUATTRO SPORT is a large, four-door executive saloon from Audi, aimed at buyers wanting more space and comfort than a family hatchback. In the UK used-car market it sits among older premium cars, once competing with BMW 5 Series and Mercedes-Benz E-Class models. With a powerful turbocharged engine and quattro four-wheel drive, this A6 is distinctive for strong performance and reassuring grip, especially in poor weather. The roomy cabin and boot make it suitable for comfortable commuting, longer journeys and small families, while its age and performance mean it may cost more to run than a modest everyday saloon.
