The AUDI A4 (2001-05) 5DR AVANT 3.0 QUATTRO SE is a five-door estate, rather than a hatchback or SUV, offering A4 saloon comfort with useful extra load space. In the UK used-car market it is now an older premium family car, appealing to drivers wanting a practical wagon at modest purchase prices. Quattro four-wheel drive and the smooth 3.0-litre petrol engine distinguish this SE from more ordinary A4 estates, giving reassuring grip and relaxed performance, though fuel costs are likely higher than with smaller-engined rivals. It suits families, touring couples and anyone carrying luggage or outdoor gear, while its composed drive and cabin feel make longer journeys more appealing than city-only use.
