Mercedes-Benz C Class prices in the UK

The average used Mercedes-Benz C Class listed for £15,239 in the UK as of July 2026 (median £13,500), based on 13,538 ScanAuctions price observations. The value sweet spot is a 2015 car at around £9,773 — 23.7% less than a 2016.

The C Class in the used market

The C-Class market is stacked with ex-company C220d saloons, which keeps supply deep and prices rational. W204 cars (2007–2014) are the budget end with well-documented injector and steering-lock folklore; the W205 (2014–2021) is the volume sweet spot, with air-suspension cars needing a careful overnight-sag check. Estates carry a small but consistent premium over saloons.

Value sweet spot: 2015. A 2015 Mercedes-Benz C Class averages £9,773 — 23.7% less than a 2016 — the biggest one-year price drop on this model.
