The AUDI A4 (2001-05) 5DR AVANT 1.9 TDI 130 SPORT is a five-door estate, offering a useful alternative to a family hatchback with more room for luggage. In the UK it sits among premium mid-sized estates, competing with the BMW 3 Series Touring and Mercedes C-Class Estate, but often appeals as a practical used buy. The 130-horsepower diesel is known for relaxed, economical long-distance driving, while the Sport trim gives the A4 a more purposeful feel. It suits commuters and families needing a comfortable everyday car with estate versatility. Mycarcheck recorded 22 look-ups across 16 VINs, a useful but modest snapshot of interest. Checks show average mileage of 161,000 and roughly 5,000 miles driven yearly; cars average just over five previous keepers. The £300 average private-sale valuation is a check-data figure, not a guide price. Against rivals, it offers roomy boot space and efficient diesel character, though age and condition matter greatly.
