Meet the 2018 BMW M3 Sedan: Competition Package Included
Feast your eyes on a 2018 BMW M3 sedan, a mechanical beast set apart by its striking Competition Package, now at 33k miles since the seller snagged it in 2021. Under the hood, we’ve got a twin-turbocharged 3.0-liter S55 inline-six engine, happily mated to a six-speed manual transmission. This beauty’s dressed in Black Sapphire Metallic with black Merino leather inside, boasting features that would make a Fiat Fullback blush with envy.
Glistening with Gadgets
The car’s like a rolling commercial for opulence—Active M differential, 20″ Style 666M alloy wheels, and dazzling Icon Adaptive LED headlights. Then there’s the creature comforts: heated seats front and rear, a steering wheel that warms up too, Harman Kardon sound system, and Park Distance Control that’s more adept than most humans. They even threw in navigation and Comfort Access keyless entry for good measure. Fast forward to June 2025, the stylish M3 had some wheel refurbishing, fresh tires, and new drive belts. Ready for a new family.
Check Out the Exterior Styling: Might Need Sunglasses
Unlike the basic 3-series, the F80 M3 distinguishes itself with widened bodywork, slick fender vents, and those iconic bumpers we’d expect from a car flaunting its Competition badge. The gloss-black kidney grilles and side gills add a touch of drama, while the Shadowline trim and carbon-fiber roof shout performance at the top of their lungs.
Exterior Features to Note

Wheels That Speak Volumes: 20″ Style 666M Alloy Wheels
Originally refinished in June 2024, these wheels are shod with Michelin Pilot Super Sport tires. The Competition package turns things up by introducing a quicker steering ratio, stiffer springs, and anti-roll bars. Not to mention the revisions to the Adaptive M Suspension and stability control settings. Braking, unsurprisingly excellent, is managed by blue-finished M-branded caliper stopping cross-drilled rotors.
Interior: A Synonym for Luxury
Diving into the lap of luxury, the M3 treats you to black Merino leather upholstery wrapped around the cabin. It’s graced with carbon-fiber trim across the dashboard and center console. Toss in the heated, power-adjustable sport seats, head-up display, and a dream-like Harman Kardon sound system, and you’ve got yourself a cabin even a Cadillac would tip its hat to.
Additional Interior Goodies
- Comfort Access keyless entry
- Dual-zone automatic climate control
- Cruise control
- iDrive infotainment with navigation
Now, About That Speedometer
Sitting pretty behind a leather-wrapped steering wheel, drivers get a 200-mph speedometer to drool over, alongside an 8,500-rpm tachometer and all the gauges you need to keep track of oil temp and fuel level. The digital odometer speaks of 33k blissful miles, with about 1k of those added by the current owner.
Under the Hood: S55 Inline-Six Powerhouse
The S55 inline-six engine is the pride and joy of this M3, boasting 444 horsepower and a torque of 406 lb-ft in Competition spec. Not just a pretty face, it’s a force of nature.
June 2025 saw an overhaul with the replacement of drive belts, a shot of fuel induction service, and an oil change. The M3 sings like a well-oiled machine and accelerates with a thrill that’s the stuff of legends.
It’s All About the Drive
Power flows seamlessly to the rear wheels via a six-speed manual transmission and Active M differential. For those who love staying in control, it’s a joyous dance of precision, hustle, and top-notch engineering. After all, the differential fluid got a refresh, making those sharp turns silky smooth.
Carfax Says: Clean
Last but certainly not least, the Carfax report clears this M3 of any accidents or damages. So, what’s not to love? The 2018 BMW M3 with Competition Package is one for the ages.
