At just 16,000 km, this X7 xDrive40d M Sport arrives as one of the cleaner low-mileage examples of BMW's flagship SUV available in the current market, and the specification it carries makes that condition all the more worth noting. Power comes from BMW's 3.0-litre TwinPower Turbo diesel straight-six, producing 335 HP and 700 Nm of torque, sent through an eight-speed M Steptronic transmission and BMW's xDrive All-Wheel Drive system, giving it the kind of relaxed, long-legged pace that suits the car's character perfectly. The M Adaptive Air Suspension works across multiple drive modes to keep the ride composed whether the roads demand comfort or a more purposeful approach, and the Laserlight headlights with adaptive beam and Active Cruise Control with Stop and Go make extended motorway runs genuinely unhurried. Inside, the Premium Merino Leather interior in Tartufo is complemented by an Alcantara headliner, while all three rows of the seven-seat configuration come with heated, ventilated, and massage seating, a level of rear-cabin consideration that few rivals match. BMW Live Cockpit Professional with iDrive 7.0, Touch Controller, and Gesture Control sits at the centre of the driving experience, supported by Wireless Apple CarPlay and Android Auto and a Harman Kardon surround sound system that does full justice to the cabin's quality. The Panoramic Sunroof, Powered Tailgate with Gesture Control and Kick Sensor, Blind Spot Monitor, and Lane Keep Assist complete a specification that has been thought through rather than merely ticked off. As a whole, this is a thoroughly equipped, low-mileage example of one of BMW's most capable large SUVs, and it presents as a vehicle that has plenty left to give.
