Mercedes-Benz A-Class buying guide (Ireland, 2026)
What a used Mercedes-Benz A-Class costs in Ireland, how it does at the NCT, what goes wrong and what it costs to fix. Based on 790 for sale right now.
Our take on the Mercedes-Benz A-Class
A 2023 Mercedes-Benz A-Class typically advertises at €34,300 and a 2018 one at €18,900, so it loses roughly 11% of its value a year at that age. At the NCT, the 2009–2021 cars do better than other cars the same year. The 1.6 petrol is the most common engine (35% of those with a known engine), and it usually lasts around 300k km.
