AI Market Summary

Diesel engine is efficient for motorway miles; expect strong real-world fuel economy and low tax relative to petrol peers.
Market pricing up 28% year-on-year — strong demand but check comparable petrol models, which often undercut diesel by €500–€1000 now.
Mazda 6 diesel (2018) is generally robust; no widespread engine or gearbox defects reported, but injector and DPF maintenance costs rise after 160k km.
Before purchase, have a full diagnostic scan run — confirm DPF regeneration history and check for any turbo lag or rough idle on cold start.
Inspect service history closely; irregular servicing on a diesel at 165k km can hide costly repairs ahead — ask for proof of oil changes and filter replacements.

Important caveats

NI import estimates assume the car is NI-registered (not GB-origin). GB-origin cars add customs duty (6.5%) + import VAT (23%), potentially €3,000–€6,000 more.
Revenue may assess a different OMSP than the ROI median shown above.
NOx levy for diesel can vary from €600 to €3,500+ depending on the vehicle's individual emissions figure.
Cars 4+ years old require an NCT before ROI registration.
Always verify the V5C registration history and get a quote from Revenue.ie before purchasing.
