A wildly modified 2007 BMW 328xi Sports Wagon, now powered by a Maserati 4.7-liter V8 and a Nissan CD009 six-speed manual, has landed on Cars & Bids with a current bid of $9,000. Finished in Sparkling Graphite Metallic and sitting on 19-inch Volk TE37SL wheels, the long-roof BMW has been transformed into a one-off European-Japanese-Italian mash-up that blends a Ferrari-related engine family with E9X M3 hardware and custom fabrication throughout. The chassis shows 143,800 miles, though the swap and supporting components were installed only a few months ago.
For BMW fans used to seeing more conventional builds on the market, like the new lease deals for the BMW X3 or clean M models such as the 2011 BMW M3 Convertible, this 328xi wagon heads in the opposite direction, leaning fully into enthusiast-engineered chaos.
The Maserati V8 Swap and Full Drivetrain Conversion
Under the hood sits the Maserati F136 4.7-liter V8, factory-rated at 433 horsepower and shared with models like the Quattroporte and GranTurismo. It has roughly 85,000 miles on it and breathes through a Maserati 4200 intake manifold wearing a Ferrari badge, a K&N filter, custom stainless fuel lines, and a full E9X M3 catless exhaust system with headers. Fuel and spark are controlled by an ECUMaster standalone ECU.
The original xDrive and factory transmission are long gone. In their place is a Nissan CD009 six-speed manual using a Speed Gems adapter, a custom clutch rated to 600 hp, a stainless clutch line, a 7/8-inch master cylinder, and a custom driveshaft. A manual steering-rack conversion completes the drivetrain overhaul, turning the wagon into a rear-drive, high-revving V8 sleeper.
This kind of high-effort swap sits closer in spirit to limited-run track specials, like the 2016 BMW M4 GTS, than any stock 3 Series wagon ever built.
Exterior, Interior, and Chassis Details
The wagon wears an aggressive mix of M3 and aftermarket parts, including an E9X M3 front bumper, fenders, side skirts, mirrors, core support, a carbon crash bar, and an M-Sport rear bumper. A Seibon carbon-fiber hood (also wearing a Ferrari badge), aftermarket LED headlights, smoked reflectors, red taillight overlays, and a custom rear diffuser sharpen the look further.
Inside, the factory wagon has been replaced almost entirely with performance components: Recaro Sportster seats on powered bases, an E9X M3 steering wheel, a Serial Nine CD999 shifter, Alcantara trim pieces, a carbon-fiber weighted shift knob, an F8X-style head unit, and custom A/C routing with a hidden on/off switch.
Chassis upgrades include E9X M3 front brake calipers and rotors, H&R lowering springs, a manual steering-rack kit, and of course the lightweight Volk wheels. Known flaws include scratches on the passenger doors, a ding on the rear quarter, some interior wear, and active 4×4/ABS/brake warning lights, the seller says the FRM and CAS modules need coding.
Why It Matters
Engine-swapped BMW wagons are already rare, but a Maserati F136 V8 paired with a CD009 manual gearbox and full M3 running gear pushes this one into truly unusual territory. For enthusiasts seeking a wagon with character, noise, and the sort of “why not?” engineering spirit normally found in grassroots motorsport, this 328xi offers massive uniqueness per dollar.
With fresh major work completed just months ago and an extensive parts list, it’s positioned as a high-effort, high-personality build that could appeal to anyone wanting a sleeper wagon with supercar-source material under the hood.
