The AUDI A4 (2001-05) 5DR AVANT 1.8T SPORT is a five-door estate, offering more luggage space than the saloon while keeping a relatively tidy footprint. In the UK used-car market it sits as a premium family car, aimed at buyers wanting a practical load carrier with a smarter, more upmarket feel than an ordinary estate. mycarcheck.com recorded 18 look-ups covering seven different VINs, so its figures are a small snapshot rather than a full market guide. Those checks show an average recorded mileage of 149,000 miles, around 6,000 miles a year, and about four to five previous keepers. The average private-sale valuation was £300; treat this as a check-data average, not a current asking-price recommendation. The 1.8T feels lively on commutes and longer trips; its estate body suits families or anyone carrying bulky kit. It balances comfort, polish and practicality, with premium BMW 3 Series Touring and Volvo V50 rivals.
