AUDI A6 (1997-04) 5DR AVANT 2.5 TDI 180 QUATTRO SPORT
Buyer's Guide & Data from our Checks
The AUDI A6 (1997-04) 5DR AVANT 2.5 TDI 180 QUATTRO SPORT is a large, premium estate, designed for buyers needing more space than a saloon without moving to an SUV. In the UK, it competed with executive estates such as the BMW 5 Series Touring and Mercedes-Benz E-Class, offering a practical, understated alternative.
The 2.5-litre diesel and four-wheel-drive Quattro system give it confident, composed progress, especially on longer journeys and in poor weather. Its roomy cabin and generous load area suit families, regular commuters and anyone who travels with bulky kit. It feels more substantial and comfort-focused than a typical family estate, while its strong diesel character favours relaxed cruising over town-car agility.
