2021 BMW 420I Xdrive M Sport Auto 2.0L Petrol · K31 FME

The 2.0-litre petrol engine offers a balanced mix of performance and efficiency, though real-world fuel economy will depend heavily on your driving style and the use of the xDrive system. You should budget for premium-grade fuel to maintain engine health and performance.

As a 2021 vehicle, it will be subject to the standard VED rates for cars registered after April 2017. Insurance will fall into a higher grouping due to the M Sport trim and performance capabilities, so obtain quotes before finalising your purchase. Annual maintenance should be manageable, but keep in mind that BMW parts and labour costs are higher than those of non-premium brands.

While the MOT history is flawless with no defects, you should still perform a physical inspection of the bodywork, particularly the alloy wheels, which are prone to kerbing on M Sport models. Inspect the underside for any signs of damage or leaks, especially around the transfer case and differential components associated with the xDrive system.

Test the automatic transmission through all gears to ensure smooth shifting without any hesitation or clunking. Verify that all safety features, including parking sensors and cameras, are fully operational, as these can be costly to repair if they develop faults after the warranty period expires.
