The AUDI A6 (1997-04) 5DR AVANT 1.9 TDI 110 is a large five-door estate, known as the Avant, from Audi’s executive-car range. In the UK used market it offers more load space and comfort than a typical family hatchback, while remaining a practical alternative to premium estate rivals such as the BMW 5 Series Touring and Mercedes-Benz E-Class. Its roomy cabin and generous boot make this A6 estate well suited to family holidays, everyday errands and longer commutes, especially for drivers who value carrying space and relaxed distance travel. The 1.9-litre diesel is best known for economical, useful everyday performance rather than speed, making a well-kept example appealing to high-mileage commuters or budget-conscious families. mycarcheck.com has recorded just four checks, covering four VINs, so figures are indicative only: average private-sale value £500, mileage 154,000, annual use 8,000 miles and five previous keepers. Its age, space and thrift remain its main attractions.
