The AUDI A4 (2001-05) 4DR SALOON 1.8T 163 MTRON AUTO is a four-door petrol automatic in the compact executive class, positioned as a premium UK family saloon. BMW 3 Series and Mercedes-Benz C-Class were key rivals. Its smart, understated styling suits buyers wanting a traditional rather than hatchback shape. Its 163 horsepower and automatic gearbox provide relaxed, brisk driving, suiting commutes, longer journeys and small families seeking comfort and a separate boot. It feels more premium and composed than many mainstream family cars, but age makes condition, service history and running costs important to check. Across the available mycarcheck.com checks, there were seven look-ups covering two VINs, a small sample. The checks show average recorded mileage of 117,000, annual mileage of 1,000, and just over five previous keepers; average private-sale valuation was £300. These figures describe cars checked, not every example, so inspect any A4 carefully before making a purchase.
