2024 BMW 840I M Sport Auto 3.0L Petrol · YR24 TPX

Running costs for a 3.0-litre petrol grand tourer will be substantial. Expect real-world fuel economy in the high 20s to mid-30s mpg depending on driving style, and VED (road tax) will include the expensive-car supplement applicable to vehicles with a list price over £40,000 for the first five years from registration — budget for the higher annual rate until 2029. Insurance will sit in a high group given the performance, value and repair costs of an 840i.

Maintenance at BMW main dealer rates is costly, though the remaining manufacturer warranty should cover unexpected mechanical failures in the near term. Tyres for the M Sport's large alloy wheels are a notable recurring expense. Overall, a realistic annual running cost covering fuel, tax, insurance and routine maintenance is estimated at £2,500-£3,500, depending heavily on mileage and insurance circumstances.

With no MOT failures or advisories on record to guide you, inspection should focus on the fundamentals for a nearly new premium car. Examine the grey paintwork and panel gaps carefully for signs of accident repair, and check the M Sport alloy wheels for kerbing and the tyres for uneven wear, which could indicate alignment or suspension issues. Inspect the interior electronics thoroughly — the 8 Series is packed with infotainment and driver-assistance technology that is expensive to rectify outside warranty.

On a test drive, listen for any hesitation or roughness from the 3.0-litre turbocharged petrol engine and ensure the automatic gearbox shifts smoothly through all modes. Check that all recalls and software updates have been applied by asking a BMW dealer to run the VIN. Finally, verify the registration documents, VIN plates and service history all match YR24TPX, and confirm there is no outstanding finance or write-off marker against the vehicle.
