The AUDI A3 (2008-13) 3DR HATCHBACK 2.0 TDI 170 S LINE is a premium compact hatchback, sitting above mainstream small cars in the UK used market. Its three-door body gives it a sportier look than a family-focused five-door, while S line trim adds a purposeful appearance. It suits drivers wanting quality and style in a manageable size. Its 2.0 TDI diesel engine is the more powerful choice in the range, offering brisk response for motorway journeys and overtaking, while diesel running costs can appeal to regular commuters. The three-door layout is less convenient for frequent rear-seat access, so it is best for singles, couples or small households rather than families needing easy everyday practicality. Mycarcheck.com’s 662 look-ups covered 299 VINs: average mileage was 143,000, annual use 8,000 miles, keeper count 6.3 and private-sale value £1,700. Against Golf and BMW 1 Series rivals, it offers premium feel and sporty character within its class.
