BMW M42016

• Mileage is **below average** for a 10-year-old — verify service history and cylinder compression before committing; unreliable mileage data is red flag.
• M4 delivers genuine 425 hp performance and engaging dynamics, but running costs (premium fuel, insurance, maintenance) are steep; hold value reasonably well in specialist market.
• Turbocharger wastegate rattle common — listen for metallic noise under load; carbon buildup on valves degrades cold-start and throttle response; fuel pump relay weakness causes intermittent starting.
• Get pre-purchase diagnostic scan for turbo boost pressure and fuel system; inspect service receipts for carbon cleaning or turbo work already done.
• NI import saves €5,436 before VRT, NOx levy, and registration — actual saving shrinks once taxes applied; compare final on-road cost carefully.
