2018 BMW X3 M40i xDrive

Vehicle Description

This 2018 BMW X3 M40i AWD is the one that an enthusiast knows to wait for — fully loaded, in the clean machine silver on Black color combo, sitting proper on the rare and best-optioned 21" Style 718M wheels. It's equipped with the Executive Package, Premium Package, Driving Assistance Package, and individual upgrades like the Harman/Kardon surround sound, Wireless Charging, Gray Poplar wood trim, Navigation, and so much more. This X3M40i is in exceptional condiotion and completely loaded up. The M accents stiched into the seats, Heated Steering Wheel, and the Gesture Control are just a few of the long list of options that this X3M40i comes equipoped with. Its also never been in an accident and lived its whole life right outside of San Fransico CA, an area known for keeping vehicles in prestine condition compared to all of the other suspect areas across the US and Canadian vehicles.

Mechanically, the M40i deliver! The responsive BMW turbocharged inline-6 pushes 355hp through a performance-tuned xDrive AWD system the connects to any tarmac. With its adaptive M suspension, upgraded brakes, and unique exhaust tuning, this X3 M40i is a purpose-built sleeper SUV with daily-driver comfort and M-tuned soul taht can be reserected with the press of the pedal. The fact that this one comes with a perfect West Coast, no-accident, sunny-California history only solidifies its place at the top of the value-retention food chain.

Starting with the Executive Package (ZPX), this is one of the highest-tier upgrades BMW offers on the X3 lineup. It includes the massive 12.3" Dynamic Digital Instrument Cluster that transforms the entire driver cockpit into a fully animated digital display. Parking becomes effortless with Surround View and 3D View — a full top-down, rotating live camera system that eliminates blind spots entirely. Add to that Parking Assistant Plus and Active Park Distance Control, and you’re looking at one of the most intelligent parking systems on the market. You also get BMW's rare Gesture Control system, letting you adjust volume or skip tracks with just a flick of your fingers in midair — next-level tech that 99% of X3s don’t come with.

Next, the Premium Package (ZPP) brings serious daily comfort and convenience to the table. You’re looking at must-have features like the Heated Steering Wheel, Heated Front Seats, Remote Services, and BMW’s exceptional Navigation system with Advanced Real-Time Traffic. It also adds the full-color Heads-Up Display, which projects your speed, nav instructions, and driver assistance alerts right into your line of sight — no need to look away from the road. This package integrates directly into the vehicle's HUD-based warning systems and works in tandem with the Driving Assistance tech to keep you aware without distraction.

The Driving Assistance Package (ZDA) is where this M40i separates itself from lower trims and lesser builds. You get Active Blind Spot Detection, Lane Departure Warning, Frontal Collision Warning with City Collision Mitigation, and Cross-Traffic Alert Rear. These aren’t just passive warnings — these systems actively intervene when needed. Combined with the Navigation-based Speed Limit Info and Pedestrian Detection, this X3 helps prevent accidents, not just survive them. It's intelligent, proactive, and integrated in a way that elevates BMW safety tech far above the norm. It’s especially rare to find all three of these major packages stacked on the same build.

Then we have the performance side of this machine — and this isn’t your average X3. The M40i is the top-of-the-line trim for this generation, with a twin-scroll turbocharged 3.0L inline-6 (B58) that’s known in enthusiast circles for its reliability, tuning potential, and buttery smooth power delivery. It pushes 355 horsepower and 369 lb-ft of torque through a lightning-fast 8-speed automatic transmission with launch control and paddle shifters. BMW’s xDrive AWD system in the M40i is performance-tuned and rear-biased, meaning it handles more like a sports sedan than an SUV — until you hit snow or rain, when it becomes unstoppable. And the optional Adaptive M Suspension with three selectable drive modes (Comfort, Sport, and Sport+) completely changes how the vehicle feels on the road.

The aesthetics of this build also stand above the rest. Finished in the timeless Gray Metallic over Black Vernasca Leather with contrast stitching, it looks as dialed as it drives. The Gray Poplar wood interior trim adds a real sense of BMW craftsmanship — no faux carbon here. The standout feature is undoubtedly the optional 21" Style 718M wheels, staggered with 8.5" fronts and 9.5" rears, wrapped in performance rubber. These are BMW’s top-tier wheels for the X3 M40i, and they completely transform the road presence and cornering grip of the car. Most M40i builds run on 19" or 20" wheels — the 21s are a visual and functional upgrade you feel the second you turn the wheel.

Inside, you’ve got all the right luxury elements without going overboard. Wireless Charging keeps your phone powered without cables, and the Harman/Kardon Surround Sound absolutely slaps with its 600W+ audio system and premium speaker layout. It’s crystal clear at low volume, but turn it up and it handles bass and clarity like a true premium audio setup should. The Vernasca leather seating surfaces are both luxurious and durable — real leather, not the synthetic stuff found in lower trims. And the cargo space and rear legroom in the G01 chassis are more generous than in previous gens, making this a true family hauler with an enthusiast edge.

From a condition standpoint, this X3 M40i is flawless — straight-up showroom-grade. No accident history. No previous paintwork. No weird smells or wear. It’s been garaged, meticulously maintained, and owned in California its entire life, which matters more than most buyers realize. California’s dry, salt-free roads mean zero underbody rust, zero sunroof drainage issues, and none of the long-term corrosion problems you find on East Coast or Midwest cars. A clean Carfax and a history out of the ideal climate bubble translates into real value retention, real reliability, and real resale value long term.

This X3 M40i checks all the right enthusiast boxes: fully loaded, AWD, performance-tuned inline-6, 21” M wheels, HUD, Harman Kardon, Digital Cluster, Gray on Black, and perfect West Coast history. It’s also priced below market because at Supreme Motors, we don’t play the game of markups or fluff. We source rare, optioned-out, clean history West Coast cars — period.
