2015 BMW 4 Series 435i M-Sport Convertible

Vehicle Description

If you’ve been hunting for the perfect blend of performance, luxury, and timeless design in a drop-top German machine—this 2015 BMW 435i Convertible M-Sport checks every single box and then some. Finished in the highly coveted black-on-black color combo and sitting aggressively on factory 19" M Sport wheels, this west coast-owned California gem is the kind of car that gets rarer and more desirable by the year. With its legendary 3.0L inline-6 turbocharged motor mated to BMW’s precise 8-speed sport automatic transmission, the 435i delivers a driving experience that’s simultaneously thrilling and refined. This particular example was originally sold as a BMW Certified Pre-Owned (CPO) to its first owner, and its history is as clean as they come—no accidents, no paintwork, zero blemishes. That clean pedigree, especially when paired with its full option loadout, makes this one of the most investment-worthy F33 convertibles on the market today.

This 435i is powered by BMW’s legendary N55 3.0L inline-6 turbo, a motor known in enthusiast circles as one of the most reliable and tunable powerplants of the modern era. It cranks out 300 horsepower and 300 lb-ft of torque through an ultra-responsive 8-speed sport transmission, pushing this convertible from 0-60 in the low 5-second range—all while delivering surprisingly efficient MPG numbers when cruising. The M Sport suspension tightens up the handling while still remaining practical for daily driving, and the chassis feels planted and balanced whether the top is up or down. Unlike many convertibles that trade performance for flash, this 435i still drives like a true BMW should. It’s not a watered-down cruiser—it’s a properly sorted rear-wheel-drive sports machine that offers top-tier engagement without needing to jump to an M4.

Visually, the M Sport body package changes everything. The aggressive front and rear bumpers, aerodynamic side skirts, black window trim, and lower ride height separate it from the sea of base 4 Series convertibles. The Lighting Package brings Adaptive Full LED Headlights that pivot with the steering angle—legit safety tech that also gives this 435i an unmistakable presence at night. Automatic High Beams and LED fog lights add to that visibility. The 19” factory M Sport wheels are staggered for proper performance stance and aesthetics, with zero curb rash and deep tread remaining on the tires. These wheels aren’t just for show—they’re forged, lightweight, and paired with upgraded M Sport brakes that bite hard when needed. The full setup gives this car a hunkered-down, aggressive profile that stands out even in traffic.

Inside, the black Dakota leather sport seats are in excellent shape and provide firm but supportive bolstering that fits both spirited driving and longer highway trips. The M Sport steering wheel is thick and perfectly contoured, with paddle shifters in just the right place for control when you want it. This car comes loaded with the Premium Package, which includes Comfort Access keyless entry, satellite radio prep, and power lumbar for the front seats—small touches that make a huge difference in day-to-day usability. The Technology Package adds the upgraded widescreen iDrive system with real-time traffic, BMW Apps, and the coveted Heads-Up Display that projects speed, navigation, and media info directly onto the windshield. Once you get used to the HUD, you’ll never want to drive without it—it’s a legitimate performance and safety feature that most models skip.

Mechanically, this 435i is completely bone stock and unmodified—just the way it should be. No hacked-together tunes, no cut springs, no aftermarket electronics—this is a true enthusiast’s car that’s been preserved rather than molested. The power-retractable hardtop functions flawlessly and can be operated at speeds under 11mph, making it easy to drop the top at a red light or while rolling through a scenic neighborhood. And unlike soft tops, this roof keeps cabin noise to a minimum and holds up against all weather types while delivering the coupe-like profile when closed. The underbody is pristine with zero corrosion—something you just won’t find on Midwest or East Coast cars. Everything from the suspension bushings to the electrical connectors still looks and performs like it should.
