The AUDI A6 (1997-04) 5DR AVANT 1.9 TDI 130 SE is a large executive estate, rather than a city car or SUV. Its roomy five-door shape gives it practical luggage space while retaining the comfort and feel expected of a family car. In the UK used market, it appeals to buyers seeking an older, spacious long-distance car at an accessible price. mycarcheck.com records 253 look-ups and 159 distinct VINs, providing a snapshot of used-car interest. Checked examples averaged 187,000 miles, around 8,000 miles a year and about four previous keepers; the average private-sale valuation was £1,100. These figures describe the cars checked, not a guaranteed price or condition, so inspect each example carefully. The 1.9-litre diesel suits commuters and families making regular journeys; estate practicality and relaxed motorway manners are key draws. Compared with BMW 3 Series Touring and Mercedes C-Class estates, this A6 is known for space and understated comfort.
