2011 BMW 3 Series 335is

This 2011 BMW 3 Series 335is Convertible is the rare, U.S.-exclusive “s” model enthusiasts hunt for—made even more compelling by its low 51,710 miles and a timeless Black Sapphire Metallic over Black Dakota Leather specification. The 335is sits in a sweet spot between a standard 335i and the full M car, pairing the higher-output, 3.0-liter twin-turbocharged inline-six (N54) with factory hardware and calibration upgrades that transform the driving experience while keeping everything OEM and cohesive. It is also uncommon by design—roughly 4,500 335is models were produced—earning a reputation as a true sleeper thanks to its temporary overboost function, the unique availability of BMW’s 7-speed DCT in this range, and a suite of mechanical and cosmetic enhancements that set it apart the moment you press the start button.

For 2011, BMW refreshed the coupe and convertible with a cleaner, longer front fascia, new headlamps with LED corona rings, revised tail lamps and rear bumper details, and updated rocker panels, complemented inside by the latest-generation iDrive interface. The 335is adds the “go” to match the “show”: this higher-output N54 is factory-rated at 320 hp and 332 lb-ft, with an overboost feature that briefly elevates torque to 370 lb-ft under heavy load. To support the extra thrust, BMW engineered substantial cooling improvements, including additional heat exchangers and higher-performance fan logic, and paired them with sport exhaust tuning for a deeper, more assertive note and stiffer engine mounts for a tighter, more connected feel. Unique visual touches—blacked-out grille and trim, model-specific aerodynamic pieces, and the M Sport body kit—complete the 335is identity without shouting, which is exactly why enthusiasts call it a sleeper.

Open the door and you’re greeted by power-adjustable front seats with the heated option, finished in Black Dakota Leather that suits the car’s purposeful demeanor. The Premium Package ($1,650) brings a thoughtful collection of amenities: auto-dimming interior and exterior mirrors, an auto-dimming rearview mirror, BMW Assist with Bluetooth, an interior mirror with compass, lumbar support, and a universal garage-door opener. The Convenience Package ($1,250) adds daily-use upgrades that you immediately appreciate, including an alarm system, Comfort Access keyless entry, and Park Distance Control. The Cold Weather Package adds heated front seats and retractable headlight washers. Technology is intuitive and right where you need it, with an infotainment screen offering AM/FM and navigation, and the parking sensors integrate seamlessly to make tight spaces simple.

As a complete 335is, the hardware and software story is the headline. The engine’s broader, stronger torque curve and brief overboost hit are backed by factory upgrades to cooling, sport exhaust tuning, and stiffer engine mounts, while the distinctive M Sport body kit and black exterior accents identify the car to those who know without drawing unnecessary attention. The result is refined composure on the highway and immediate response when the road turns interesting—power that feels effortless, a chassis that’s buttoned-down, and a character that’s genuinely special. This particular example’s mileage underscores how sparingly it has been enjoyed, and its presentation in Black Sapphire Metallic over Black Dakota Leather is exactly what you want on a performance-focused E93 3 Series. The CARFAX is CLEAN.

If you’ve been waiting for the right 335is Convertible—one that pairs the refreshed 2011 design with the higher-output twin-turbo inline-six, the factory “s” hardware, and the right options—this is the one that checks the boxes. With rarity baked in, the coveted overboost calibration, the unique 335is upgrades, and the Premium, Convenience, and Cold Weather Packages, it delivers the understated, enthusiast-grade experience that made the 335is legendary.
