AI Market Summary

Diesel 3 offers strong fuel economy and reasonable running costs — ideal for moderate Irish mileage patterns at 15k–20k km/year.
Mid-range pricing holds steady; no significant year-on-year shift suggests fair market value — not a bargain, but stable demand reflects solid reputation.
Mazda3 diesel engines (this gen) are generally robust; no widespread defects flagged. Standard service intervals and parts availability are straightforward.
Check service history carefully — verify regular oil changes on a diesel engine, and confirm NCT compliance (next test due if not within 2 years).
At 77k km, mileage sits comfortably within expected range for a 6-year-old; no red flags on wear or authenticity.
