Our take on the Audi S3
A 2019 Audi S3 typically advertises at €32,950 and a 2014 one at €22,000, so it loses roughly 8% of its value a year at that age, slower than most cars. It's sold here mainly as a petrol. At the NCT, the 2014–2015 cars do better than other cars the same year. The 2.0 petrol is the most common engine (100% of those with a known engine), and it usually lasts around 300k km.
