LISTING OVERVIEW · check details with the seller
Seller information: “This 2021 BMW 4 Series 420i M Sport is a BMW manufacturer approved vehicle that combines performance with a refined driving experience. Under the bonnet, it features a 2.0 litre petrol engine that meets Euro 6 emission standards. The M Sport trim enhances the vehicle with specific styling and performance upgrades, including M Sport brakes with blue calipers for improved stopping power. Inside, the cabin is designed for comfort, featuring front lumbar support to assist with longer journeys. This model is designed to be practical for everyday use, offering a large boot space for luggage and shopping. It is also an efficient choice, delivering a fuel economy of 42 mpg and low CO2 emissions, which helps to reduce running costs. The vehicle is equipped with the Technology Plus Pack and Parking Assistant Plus, which provide comprehensive support through a 360 degree camera system, as well as front and rear cameras and sensors to make parking straightforward. Additionally, the inclusion of a premium branded sound system enhances the interior experience, while the low insurance group makes this a sensible option compared to other vehicles in its class.”.
