2018 BMW 5 Series M550i xDrive Sedan

Vehicle Description

This 2018 BMW M550i xDrive in the highly sought-after black-on-black color combo is the definition of executive performance. With the rare factory 20" M Sport wheels and every major option package checked, this is not your average 5 Series—this is the wolf in a tailored suit. Under the hood, it’s powered by BMW’s 4.4L TwinPower Turbo V8, pushing 456 horsepower and 480 lb-ft of torque, launching this full-size AWD sedan from 0-60 in just over 3.9 seconds. It’s not just quick—it’s brutally fast and built to dominate the highway and the mountains around the PNW. With the optional Dynamic Handling Package, this M550i adds Active Roll Stabilization and Adaptive M Suspension Professional, making it a true surgical weapon on twisty roads while still maintaining flagship comfort. The perfect Carfax-certified history, originally from California with no accidents, no damage, and no excuses, separates this one from the pack and ensures long-term value retention.

Step inside and you’re met with a full suite of luxury, tech, and performance blended together in one of BMW’s most complete interiors. This example includes the Executive Package, which gives you Icon Adaptive Full LED Headlights with automatic high beams, soft-close doors, power rear sunshades, front ventilated seats, and the legendary head-up display. The black Dakota leather with contrast stitching, matched with fine-line wood trim and brushed aluminum accents, is a true business-class cockpit with an M-powered twist. The Cold Weather Package ensures year-round comfort with heated front and rear seats, a heated steering wheel, and a heated windshield washer system—ideal for the Northwest climate. The expansive 12.3" digital gauge cluster and iDrive 6.0 system with Gesture Control, wireless Apple CarPlay, and Navigation ensure you're connected and in full control, no matter the situation.

The Driver Assistance Package and Driver Assistance Plus Package stack on top of each other to deliver the full suite of BMW’s semi-autonomous driving features. That means Blind Spot Detection, Lane Departure Warning, Active Driving Assistant, Cross-Traffic Alert, Forward Collision Warning with Active Braking, and Adaptive Cruise Control with Stop & Go. These are the real-deal features that matter—this isn’t fake fluff for a spec sheet. You’re buying actual safety and convenience that improves every drive, especially in traffic or during longer road trips. Pair that with Surround View Cameras, Active Park Distance Control, and Park Assist, and this M550i basically drives and parks itself when needed. Most M550s on the market don’t have all of these stacked packages together, especially not in a clean, California-owned, black-on-black example like this.

On the outside, the M Sport design language is perfectly executed with gloss black trim, shadowline accents, and subtle aggression that sets it apart from base 5 Series models. The 20" M Sport wheels finish the look, sitting flush in the fenders with just enough meat from the performance tires to remind you this car isn’t just a pretty face. With Adaptive M Suspension and xDrive AWD grip, this car plants power better than most sports cars on the road today. The gloss black kidney grilles, deep side skirts, rear spoiler, and M Sport bumpers front and rear all work together to give it a presence few sedans in this segment can match. This specific build configuration is rare, and because of its perfect history and clean West Coast origin, this example should be on every enthusiast's shortlist.

Mechanically, this M550i is a tank. The N63TU2 engine used in this year is a proven powerhouse, known for reliability when properly maintained—and this one has been. It features BMW’s twin-scroll turbochargers, variable valve timing, and direct injection for immediate torque and throttle response. M Sport brakes give it the stopping power it needs, and the rear air suspension ensures it rides level and smooth whether you're on the freeway or hitting switchbacks through the Cascades. Everything works as it should, no warning lights, no leaks, no stories. And because it's California-owned with no exposure to road salt or harsh conditions, the undercarriage and suspension components are in excellent condition—something most other listings can’t truthfully claim.

This is not your average 5 Series on the marketplace, and it’s definitely not one of those rental fleet units or East Coast rust buckets that got passed around and repainted. At Supreme Motors, we handpick every car based on history, condition, options, and future resale value—and this M550i checks every box. You’re getting top-tier performance, all the flagship luxury, and a full suite of modern safety and tech, all wrapped in a black-on-black colorway that never goes out of style. It’s turnkey ready, no stories, no disappointments—just a clean, honest, rare-optioned beast ready to eat up miles and carve corners.
