The AUDI A4 (2001-05) 4DR SALOON 1.8T 163 SE is a four-door, mid-sized executive saloon, offering a premium alternative to a family hatchback. In the UK it competed with the BMW 3 Series and Mercedes C-Class, for buyers wanting comfort and an upmarket feel without a large car. Its 163hp turbocharged 1.8-litre petrol engine gives brisk, relaxed performance for commuting, longer trips and family use. SE trim prioritises comfort, with a well-finished cabin and composed road manners. Compared with mainstream saloons, this A4 feels more refined, although fuel and upkeep costs may be higher than in smaller cars. Mycarcheck.com data has 17 look-ups covering 14 VINs, so its figures are a small snapshot: average recorded mileage is 132,000, annual mileage 5,000, and previous keepers about five. The £300 average private-sale valuation is unusually low and should not be treated as a dependable asking price; condition and history matter greatly when buying.
