This 2021 BMW 4 Series 420d M Sport is a remarkable find, having been cherished by just one owner from new and boasting exceptionally low mileage for its age at only 29,523 miles. This Euro 6 compliant model features a sophisticated 2.0L Diesel Hybrid engine, enhanced by mild hybrid technology and a 48v system for improved efficiency. The M Sport trim is further elevated by the M Sport Pro Package, which includes striking M Sport Brakes with distinctive red calipers, all designed to offer a refined driving experience. The M Sport designation ensures a sporty aesthetic and dynamic feel, while the inclusion of an Incorrect Fuelling Protection System adds a layer of practical reassurance. Beyond its performance and advanced technology, this BMW 4 Series offers generous boot space, making it a versatile choice for both daily commutes and longer journeys. These carefully selected features and its excellent provenance clearly set this vehicle apart from others you might find.
