This 2025 BMW 4 Series 420i M Sport is a superb example, having had only one owner since new. It boasts a powerful yet efficient 2.0 litre petrol engine, meeting Euro 6 emissions standards. This M Sport trim level comes equipped with a host of desirable features, including an electric glass sunroof, striking 19 inch M Light Double Spoke Style 995 M Bicolour alloy wheels with performance tyres, and the immersive Harman Kardon Surround Audio Sound System. The Technology Package enhances the driving experience with a Head Up Display and a 360 degree camera for effortless parking assistance, all complemented by the M Sport Pro Pack. This BMW 4 Series offers several advantages that set it apart. Its impressive fuel economy of 45 mpg means fewer stops at the petrol station, and its low CO2 emissions are beneficial for the environment. Furthermore, its low insurance group rating can help to reduce running costs. Practicality is also a strong point, with a large boot space providing ample room for luggage or shopping. These highlights demonstrate how this particular vehicle offers a superior ownership proposition compared to others in its class.
