Opel Astra buying guide (Ireland, 2026)
What a used Opel Astra costs in Ireland, how it does at the NCT, what goes wrong and what it costs to fix. Based on 498 for sale right now.
Our take on the Opel Astra
A 2023 Opel Astra typically advertises at €21,500 and a 2018 one at €9,950, so it loses roughly 14% of its value a year at that age, faster than most cars. At the NCT, the 2009–2021 cars do better than other cars the same year. The 1.6 diesel is the most common engine (35% of those with a known engine), and it usually lasts around 320k km.

Common Opel Astra problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
Automatic gearbox health · €300–€2,500
Make sure the gear changes are smooth when warm, check for a gearbox warning light and ask if the gearbox oil was ever changed.
Timing belt history · €350–€700
Ask when the timing belt and water pump were last done (usually every 160,000 km or 5–6 years). No proof = budget for it.

"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
