AI Market Summary

Diesel engines deliver strong fuel economy and low CO2 tax, ideal for mixed Irish driving; 1.5L three-cylinder is adequate but feels modest under load.
Fairly priced relative to petrol rivals; flat year-on-year trend suggests stable market. At 98k km, expect moderate wear; verify full service history to justify mid-range asking price.
DPF clogging is the headline risk on diesels doing frequent short trips or city driving—forced regens cost €400–€800. Fuel injector carbon build-up and EGR deposits also reported; check for fault codes at inspection.
Before purchase, request complete service records (especially DPF and injector work) and insist on a pre-buy OBD diagnostic scan to catch P0087/P0088 injector faults and emissions codes early.
