“Highs: Burly twin-turbo V-8, rear-drive bias to AWD system, easily blurs a landscape, relative value in its class.” - Car and Driver, First Drive, M550Xi, May 2017

Road & Track reviewers hailed the power: “The engine delivers. If judged on thrust alone, the M550i could be chiseled into 5-series Mount Rushmore. BMW's twin-turbo 4.4-liter V-8 routes 456 hp through an eight-speed ZF automatic and all four wheels (rear-wheel drive is not available). Turbo lag is imperceptible, with peak torque—480 lb-ft—available from 1800 to 4750 rpm. BMW claims 60 mph arrives in 3.9 seconds, quicker than the last-generation, rear-wheel-drive M5. We think that figure is modest. Mashing the throttle pedal recalls every interstellar travel sequence from Seventies sci-flicks, slamming you into vision-blurring speed.”

Motor Trend reviewers highlighted the comfort: “There nothing not to like about the M550i's cabin. It's as lovely as it is purposeful. In addition to the rich leather, the cabin is trimmed in classy Fineline Cove matte wood, aluminum trim, and an Anthracite-black headliner. The standard-features list is as long as a Ken Burns documentary….”

Offered here is a 2018 BMW M550XI (all-wheel drive) in Carbon Black metallic over Black Nappa leather. A Carfax one-owner, the BMW's extensive list of standard and optional equipment—including a full range of passive driver-assistance, active driving assistance, and parking assistance features—is listed on the original window sticker (and included in the gallery for reference). Showing 38,677 miles on its odometer, the car has traveled fewer than 13,000 miles per-year since being delivered new at Erhard BMW of Bloomfield Hills, Michigan. In every respect, this M550XI has been perfectly maintained.

The deep, reflective, dark-blue metallic exterior paint exhibits a like-new finish: perfectly even, free of surface flaws, and as impressive as BMW paint usually is. All body panels—including lower-body panels—are pristine. (To best assess the quality of the paint and trim finishes, please be sure to view the close-up photographs of the car in the accompanying gallery.) Every other aspect of the car's exterior is equally impressive: chrome trim on the kidney-shaped grille, matte-black air intakes, brushed-metal trim on the lower front fascia, mirror caps, and bodyside brake-vent trim (near the front fender). Tinted cabin glass is flawless as are all the lighting lenses. Tasteful badging is limited to the “X-Drive” badge and M-Performance “M550i” emblem on the trunk lid, and the BMW blue-and-white “roundel” logo centermost front and rear. “M Light-Alloy,” 19-inch, 10-split-spoke wheels are mounted with Pirelli® Cinturato P7 245/40 tires. The wheels feature BMW-logo center caps and “M” logo molded into the surface; the open-wheel design allows views of the blue-painted, "M"-branded brake calipers and ventilated brake rotors.

The BMW's interior appointments are every bit as special. Horizontal-grain, dark wood inlays grace the door trim, console, and dashboard. A jet-black headliner covers the ceiling. Seat upholstery is a very handsome combination of diamond-stitched Nappa leathers with white piping and white deviated stitching. Black carpeting covers cabin floors with both carpet mats and hard-plastic floor-protection trays also included. The multi-function “BMW” and “M”-branded steering wheel frames driver-centric analog instruments on a dashboard accented with both piano-black trim and wood inserts. The infotainment screen with exceptional graphics rises from the dash and stows when not in use. The shift lever for the automatic transmission is located on the console surrounded by wood trim, ahead of dual armrests. The overall visual and tactile impression is perfectly in keeping with the “Ultimate Driving Machine” BMW design aesthetic. (Please view the close-up photography in the gallery to assess the excellent condition of all the M550XI's interior surfaces.)

The car's trunk is clean and complete.

Under the hood, the “M Performance” 4.4-liter, twin-turbocharger V8 is as-new. The engine bay is perfectly clean and the BMW roundel emblem shines on top. Nothing is out of place and there is no evidence of any performance modifications whatsoever. Viewed from below, the chassis is pristine as well, with all protective metal components in place. The impressive dual-exhaust system is a visual highlight.

The car's identification and information tags remain mounted. Owner literature and programmed keys are included in the sale.

While the more than 180 high-definition photographs and the short walk-around-and-startup video available on the GarageKeptMotors website showcase this '18 BMW M550Xi in detail from every angle, including from below, we expect and encourage in-person inspections at our Grand Rapids, Michigan showroom. Please call to arrange an appointment in advance as our showroom is not open to the public. And feel free to get in touch anytime by phone or email if you have questions.

In late 2017, BMW debuted the all-new 2018 BMW M550i xDrive touting these amazing statistics and features: “• The Fastest 5 Series to date – 0-100 km/h in 4 seconds. • BMW M Performance TwinPower Turbo technology engine delivering 455 horsepower and 480 lb-ft of torque. • BMW M specially tuned chassis deliver even sharper steering responses. • BMW xDrive with rear-wheel bias combines sporting dynamics with everyday practicality.”

Sounds like the sort of automobile to put a smile on your face for a very long time to come.
