AI Market Summary

Strong petrol engine performance and sharp handling; high-spec infotainment and premium interior appeal to Irish drivers seeking sporty four-seat comfort.
Median price tracking upward (+8%) suggests solid demand, but verify mileage sits within 60k–110k range—outliers signal data gaps or undisclosed issues.
Carbon buildup on direct-injection valves is common 40k–80k miles; budget €400–€800 for preventative cleaning around 60k km to avoid rough idle and power loss.
Inspect sunroof seals and drainage tubes for blockages or water ingress—critical in Irish damp; test all iDrive functions (screen lag, freezes, software crashes reported).
Reliability score trails class average; prioritise pre-purchase inspection and extended warranty if mileage approaches 100k km and service history gaps exist.
