What a used Mazda MAZDA3 costs in Ireland, how it does at the NCT, what goes wrong and what it costs to fix. Based on 147 for sale right now.
Our take on the Mazda MAZDA3
A 2021 Mazda MAZDA3 typically advertises at €19,950 and a 2016 one at €8,900, so it loses roughly 15% of its value a year at that age, faster than most cars. At the NCT, the 2019–2020 cars do better than other cars the same year. The 2.0 petrol is the most common engine (58% of those with a known engine), and it usually lasts around 350k km.

Common Mazda MAZDA3 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.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 2.0 Petrol | ~350k km | ~€420 | 63 |
| 2.5 Petrol | ~350k km | ~€1,250 | 15 |
| 2.2 Diesel | ~220k km | ~€280 | 15 |
| 1.5 Diesel | ~320k km | ~€190 | 9 |
| 1.8 Diesel | ~320k km | ~€200 | 6 |
2.2 Diesel: usual problem: oil dilution and turbo wear if the DPF regenerates badly.
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
