AI Market Summary

Refined, efficient petrol engine with strong performance; solid build quality and cabin comfort for its class.
Mid-market pricing around €18,888 is fair for mileage and age—not undervalued, but not overpriced against rivals.
9-speed auto can hesitate or shift roughly at low speed; electrical gremlins (infotainment, cluster, windows) are common; air suspension repairs are costly.
Before buying, test the gearbox through tight manoeuvres and verify all electrics (windows, infotainment, warning lights) work smoothly.
Request full service history and confirm NCT status; at 9 years old, next test may be imminent or due.
