AI Market Summary

Proven compact SUV platform with strong depreciation curve; petrol engines are simpler than equivalent diesels and avoid DPF issues.
Mid-range pricing reflects solid demand—not a bargain, but fair value for age and mileage at Irish market rates.
2018 model generally reliable; no major recalls logged. Monitor water pump (known wear item around 150k km) and DSG gearbox fluid condition if dual-clutch equipped.
Before purchase, request full service history and have a pre-buy diagnostic scan to check emissions systems—any warning lights will cost money.
Check NCT expiry and condition: these cars hold value partly on condition, so factor in tyres, brakes, and interior wear against asking price.
