The AUDI A4 (2001-05) 4DR SALOON 1.9 TDI 130 QUATTRO is a compact premium four-door saloon, aimed at buyers wanting more refinement than an ordinary family car without moving to a larger executive model. Its diesel engine and four-wheel drive make it a distinctive used A4 in the UK market, where saloons appeal to commuters and families needing a conventional boot. Mycarcheck.com recorded just three checks, covering three different VINs, so these figures offer a small snapshot rather than a reliable market-wide picture. The cars checked averaged £400 in private-sale valuation and 167,000 miles, with annual mileage of 6,000. They had averaged 4.3 previous keepers, making vehicle-specific history especially important. It suits drivers covering journeys who value all-weather traction and an understated cabin; check condition, service records and running costs before buying. Against rivals such as BMW 3 Series and Mercedes C-Class, quattro grip is a distinctive advantage for this diesel saloon.
