AI Market Summary

Solid mid-size SUV with strong driving dynamics, good visibility, and robust diesel engine when well-maintained—popular choice holds value well on Irish market.
Priced fairly relative to rivals (BMW X3, Audi Q5 same age); recent +12% annual uplift reflects diesel demand recovery, but watch for outliers above €29,900.
DPF regeneration is the critical weak point—mainly affects cars doing frequent short trips under 30 km. Fuel injector carbon and EGR valve sticking also reported; full service history essential.
Before purchase, obtain detailed service records and request a DPF/emissions diagnostic test; rough idle or power loss suggests injector fouling or EGR trouble.
