The AUDI A4 (2001-05) 5DR AVANT 2.5 TDI 180 QUATTRO is a premium five-door estate, offering more load space than the A4 saloon while remaining easier to park than a large family SUV. In the UK used-car market, it sits among alternatives such as the BMW 3 Series Touring and Mercedes C-Class estate. With its strong 2.5-litre diesel engine and quattro four-wheel drive, this A4 is suited to motorway commuting, long-distance journeys and family trips, especially where extra grip is welcome. The Avant body brings practical luggage room, while the powerful, confident feel gives it a more engaging character than many sensible estate cars. It is best for buyers who value space, comfort and all-weather reassurance, and can budget for an older, higher-mileage car. Mycarcheck.com has four look-ups across three VINs, so figures are a small snapshot: recorded mileage averaged 164,000, with 6.25 previous keepers and a £400 private-sale valuation.
