The AUDI A4 (2001-05) 5DR AVANT 2.5 TDI 155 SE is a five-door estate car: a more practical alternative to the A4 saloon, rather than an SUV or hatchback. It brought Audi’s premium feel to the UK family-car market, with useful load space for shopping, luggage and everyday jobs. The 2.5-litre diesel gives the A4 Avant a relaxed, strong-running character that suits motorway commuting and longer trips, while the SE trim adds an appealing comfort-focused feel. It is best suited to families, commuters and buyers wanting a sturdy, understated estate with more refinement than many mainstream alternatives. Against rivals such as the BMW 3 Series Touring and Mercedes-Benz C-Class Estate, the Audi is known for its composed drive and smart, discreet cabin. Mycarcheck.com recorded five look-ups across two VINs: average mileage was 153,000, annual use 6,000 miles, five to six keepers, and a £400 average private-sale valuation; treat these figures cautiously.
