This stunning 2018 BMW 4 Series Gran Coup 430i M Sport Auto is a beautifully presented, tastefully modified example finished in sleek gloss black with matching black heated leather interior. Powered by the refined and responsive 2.0-litre turbo petrol engine (Euro 6) paired with a smooth automatic gearbox, it delivers the perfect blend of power, comfort and efficiency. Maintained with full service history and in excellent mechanical condition, this car has been enhanced with a collection of premium, professionally installed upgrades that take it far beyond standard specification. It features a factory-fitted panoramic sunroof that opens and closes smoothly, flooding the cabin with light and adding a luxurious open-air feel. The interior showcases a custom-fitted starlight roof with Sky Lounge ceiling, full ambient lighting across the cabin and footwells with adjustable colours, and a hard-wired 24-hour front and rear dashcam system neatly installed through the roof with no visible wires. Technology has been upgraded with Apple CarPlay touchscreen MMI, and a built-in global GPS tracker (70/year subscription) allowing live worldwide tracking directly from your phone. A Stage 1 remap enhances throttle response and performance while retaining BMW's signature smoothness and reliability. Factory M Sport highlights include front and rear parking sensors, genuine heated electric seats, M Sport styling, dual-zone climate control, cruise control, LED headlights, M Sport steering wheel with paddle shifters and 18-inch M Sport alloy wheels. The car drives beautifully, feels solid and refined, and has clearly been cherished throughout its life. Tyres, brakes and suspension are all in excellent condition, with the interior remaining spotless, odour-free and well-kept. There is a small cosmetic dent above the right-rear light (camera evidence available) which is purely visual and does not affect performance. Private registration is not included and will revert to the original plate YH18 GFY. A genuinely well-maintained, high-spec, luxury Gran Coup that stands out from every standard 4 Series combining performance, comfort and elegance in one exceptional car. Viewings welcome by appointment; first to see will buy.
