2021 BMW 3 Series M340i Sedan

Vehicle Description

Offered by Supreme Motors in Auburn, Washington—recognized across the Northwest for delivering the highest quality vehicles at the best prices—is this pristine, one-owner w/immaculate history/Carfax 2021 BMW M340i xDrive finished in the jaw-dropping Portimao Blue Metallic over the special optioned Black Vernasca Leather with blue M stitching. This example isn’t just well-specced—it’s perfectly dialed. Backed by a clean Carfax and California-owned from day one, it features the coveted M-Sport Package on factory special edition 19" M wheels, the Premium Package with Heads-Up Display, Comfort Access, and a Heated Steering Wheel, the Connected Package Pro with wireless Apple CarPlay and live updates, and the full Driving Assistance Suite with Blind Spot Monitoring and Lane Departure Warning. Toss in the highly sought-after Harman/Kardon Surround Sound System, both factory BMW keys, the M interior trim, the color changing interior Ambient Lighting Package and the factory-tuned B58 turbocharged inline-6 producing 382 horsepower, and you’ve got one of the most complete, enthusiast-grade M340i builds on the market. This is the kind of no-compromise performance sedan that holds value, drives like a dream, and sets the bar for luxury sport daily drivers—and Supreme Motors has it.

What truly sets this M340i apart from the rest—and what can’t be overstated—is its flawless, one-owner history paired with a perfect service record from none other than Sterling BMW in Newport Beach, one of the most prestigious BMW dealerships in the country. No accidents, no damage, no excuses—this car is as clean as they come, and that matters big time when it comes to long-term value and resale. One-owner vehicles like this are worth thousands more than their 2-, 3-, or 4-owner counterparts with blemishes or inconsistent maintenance histories. Why? Because the original owner is the one who buys it brand new, sets the tone, and takes pride in the vehicle—they don’t skip services, they garage it, they protect it. We’ve found that one-owner, no-accident vehicles hold up like they’ve got 20,000–30,000 fewer miles than the same car with multiple owners or a questionable past. This particular M340i had an original MSRP right around above $61k so they were out the door around $70k for this M340. With all the right options like Premium Package, Driving Assistance Package, Connected Package Pro, Harman/Kardon, Heads-Up Display, Heated Steering Wheel, and more; this isn’t just a great spec, it’s a textbook example of a properly cared-for, highly optioned, West Coast-owned performance sedan that stands head and shoulders above the rest.

Let’s talk performance. The 2021 M340i xDrive features BMW’s revered 3.0L B58 TwinPower Turbo inline-six engine pushing 382 horsepower and 369 lb-ft of torque, mated to the smooth and responsive ZF 8-speed transmission with paddle shifters and launch control. This is a rear-biased AWD system that works in harmony with BMW’s adaptive M suspension to provide insane grip when needed, but the ability to let the rear end rotate naturally under spirited driving conditions. 0-60 times hover right around 4.1 seconds, and the powerband is incredibly linear thanks to the single twin-scroll turbo setup. This is one of the most durable and tuner-friendly motors BMW has produced, known for reliability and performance without the common maintenance headaches of past generations. Mechanically, this M340i is untouched, never modified, and serviced on schedule, which is becoming harder to find in enthusiast-level performance sedans.

The exterior styling is pure aggression and balance. The optional 19" M-Sport double-spoke wheels give the perfect stance and visual weight, matching the M-Sport bumpers, side skirts, black Shadowline trim, and gloss black dual exhaust outlets. The Portimao Blue Metallic paint is deep and vibrant, especially under natural sunlight—no peeling, fading, or prior paintwork anywhere. LED adaptive headlights with cornering function, the signature L-shaped DRLs, and LED fogs give it a signature look both day and night. The Premium Package also adds comfort access keyless entry, remote start, and the panoramic head-up display—one of the most useful features for daily use and long drives alike. Subtle black window trim, rear lip spoiler, and M badging round out a clean, factory-enhanced sport sedan that looks as fast as it drives.

Inside the cabin, the black Vernasca leather is soft, supportive, and in like-new condition—no bolster wear, fading, or scratches. The aluminum tetragon trim paired with the ambient lighting system (customizable in multiple colors) sets a modern yet aggressive interior tone. This M340i also features the Premium Package with power heated front seats, lumbar support, and a heated steering wheel—huge value adds that are often skipped on base models. The Harman/Kardon premium surround sound system brings studio-level clarity and depth to your favorite playlists, streaming via Apple CarPlay or Android Auto. Wireless charging, navigation, and real-time traffic updates are all seamlessly integrated via the Connected Package Pro. Fit and finish throughout is tight, with high-end materials used across all touchpoints, including stitched leather dash inserts and M-logo embossed door sills.

Technology and safety features were not overlooked. The Driving Assistance Package includes active blind spot detection, lane departure warning, and forward collision mitigation with pedestrian detection. The parking sensors front and rear are paired with a high-resolution backup camera, and BMW’s Parking Assistant makes tight spots a breeze. On the tech front, BMW’s iDrive 7.0 system with voice activation, over-the-air updates, and an intuitive interface remains one of the best infotainment systems in the industry. The digital gauge cluster is fully configurable, displaying everything from real-time boost pressure to navigation prompts, adding to the cockpit-like feel. The heads-up display, part of the Premium Package, projects key info like speed, navigation, and media directly onto the windshield so you never have to take your eyes off the road.
