The AUDI A4 (2001-05) 4DR SALOON 1.8T 163 is a four-door, petrol-powered family saloon, sitting in the UK’s compact executive-car class rather than the hatchback or SUV market. Its understated styling and comfortable cabin made it a rival to the BMW 3 Series and Mercedes-Benz C-Class, with useful everyday practicality. The turbocharged 1.8-litre engine gives the A4 stronger pace than a basic family saloon, while its settled ride and roomy boot suit commuting, longer journeys and families. It is best for drivers seeking a refined used car with more comfort than a budget runabout, and is comfortable on longer trips. mycarcheck.com has only two look-ups for this model, covering one VIN, so its figures are a small snapshot: an average recorded mileage of 123,000 and four previous keepers. Its £300 average private-sale valuation is sample-based, not a guaranteed price; condition, history and maintenance matter greatly when assessing any example.
