Mercedes-Benz A Class prices in the UK

The average used Mercedes-Benz A Class listed for £15,658 in the UK as of July 2026 (median £14,770), based on 19,854 ScanAuctions price observations. The value sweet spot is a 2017 car at around £10,592 — 16.6% less than a 2018.

The A Class in the used market

Today's used A-Class market is almost entirely the hatchback era: the W176 (2012–2018) made the A-Class a premium hatch, and the W177 (2018 on) added the tech that keeps its prices strong. PCP was the default way these were bought new, so ex-finance returns flood the market and keep supply deep. The plentiful automatics are dual-clutch — a smooth test drive matters more here than on most rivals.

Value sweet spot: 2017. A 2017 Mercedes-Benz A Class averages £10,592 — 16.6% less than a 2018 — the biggest one-year price drop on this model.
