This 2025 BMW 4 Series 420i M Sport is a refined example of the popular coupe, presented with the benefit of having had only one owner from new. Under the bonnet, it features a 2.0 litre petrol engine that meets Euro 6 emission standards, ensuring it remains compliant with current environmental regulations. The M Sport trim level provides a distinct aesthetic and specification, while the inclusion of the M Sport Pro Pack enhances the overall driving experience. Inside, the cabin is equipped with the Comfort Pack, which adds convenient touches such as keyless entry and wireless phone charging, alongside front lumbar support for added comfort on longer journeys. The exterior is finished with sun protection glass, and the vehicle also includes the Driving Assistant system to support the driver on the road. This model stands out in its class by balancing performance with practical everyday usability. It offers a large boot space, making it a versatile choice for those who need more room than a typical coupe might provide. Efficiency is a key strength, as the vehicle achieves 44 mpg and maintains low CO2 emissions, which helps to keep running costs manageable. Furthermore, it sits in a low insurance group, offering a more accessible ownership proposition compared to many other vehicles in the premium segment. These combined attributes make it a well-rounded option for drivers seeking a blend of style, economy, and modern technology.
