AI Market Summary

Practical family hauler with excellent space, seven seats, and flexible seating — ideal for Irish families needing genuine versatility over four-seater rivals.
Fairly valued at median price; strong year-on-year demand (+25%) suggests buyers see fair-market pricing, though mileage near upper range warrants negotiation on older examples.
DPF clogging is the critical weak point on this engine — frequent short urban trips increase risk. Injector sticking and EGR carbon faults also common; check service history for DPF regeneration records and any fault codes before committing.
Request a full diagnostic scan (€60–€100 at specialist) focusing on stored and pending DPF, EGR, and fuel system codes; a clean report is non-negotiable given known issues.
Verify NCT pass date and any advisories logged — a recent fail on emissions or exhaust systems is a red flag for this generation.

Diesel servicing is straightforward but DPF and EGR maintenance can escalate costs; synthetic oil and short intervals (10k km) help mitigate injector and turbo wear. Budget €600–€1,200 for DPF cleaning if regeneration fails.
