The AUDI A4 (2008-12) 5DR AVANT 1.8 TFSI 160 S LINE SPECIAL EDITION MTRON AUTO8 is a five-door estate, offering more luggage room than the A4 saloon while keeping a smart, executive-car feel. In the UK used market, it sits among premium family estates, competing with BMW 3 Series Touring and Mercedes-Benz C-Class Estate. The 1.8-litre petrol engine and automatic gearbox make it a comfortable choice for commuting, longer journeys and family duties, while the Avant body suits holidays and everyday shopping. S Line trim gives this A4 a sportier appearance and a more purposeful character, without sacrificing the practical, understated design that has made the model a familiar alternative to mainstream estates. mycarcheck.com has recorded five look-ups across four VINs, so this is a small sample: those checks show an average private-sale valuation of £4,700, mileage of 107,000 and 4.6 previous keepers.
