AI Market Summary

Compact luxury SUV with strong build quality, intuitive infotainment, and excellent seating flexibility for families needing extra space without full 7-seater bulk.
Priced fairly for the market — no obvious overvaluation, but diesel costs offset by reasonable depreciation. Petrol alternative worth comparing if low annual mileage.
DPF clogging is the critical diesel weak point: forced regeneration cycles cause fuel consumption spikes and warning lights around 80k km. Budget €400–800 for professional cleaning if needed; EGR valve carbon build-up also common on higher-mileage examples.
Before buying, request full dealer service history and ask specifically about DPF cleaning or regeneration cycles already done. A car at 103k km without documented maintenance is a red flag.
Median mileage aligns with Irish driving patterns — no concerns about reliability or wear at this usage level if maintenance is evident.
