The AUDI A4 (2005-08) 4DR SALOON 1.8T QUATTRO 163 S LINE is a compact executive four-door saloon, aimed at buyers wanting a more premium alternative to mainstream family cars. Its 1.8-litre turbo petrol engine and four-wheel-drive system give it a confident, engaging feel, while S line trim adds a sportier look. It sits in the same used-car class as the BMW 3 Series and Mercedes-Benz C-Class. Mycarcheck.com has recorded 60 look-ups covering 17 different VINs, a useful but modest sample. Checks show an average private-sale value of £900 and a typical recorded mileage of 117,000 miles. Average annual mileage is 4,000, and cars had 5.6 previous keepers on average, making a thorough history check worthwhile. It suits commuters and small families wanting comfort and extra grip in poor weather, though running costs may exceed those of a simpler saloon. Its sporty feel and all-weather confidence stand out.
