This 2002 BMW M3 coupe has had a claimed $97k worth of modifications performed. Highlighting the modifications is the Active Autowerke Stage 2 supercharger for the rebuilt 3.2-liter inline-six, which has forged internals and produced a peak output of 612.84 horsepower at the wheels after the build. Supporting modifications were performed to the subframe, suspension, braking, exhaust, and fuel systems, and it rides on 19″ ZCP-style wheels and also is equipped with gray leather upholstery, front splitters, a six-speed manual transmission and a limited-slip differential, and more as described below. Now with 30k miles, this modified E46 M3 is offered in California at no reserve with records, spare parts, and a clean Montana title.

The car is finished in Schwarz 2 (668) and features Shadowline trim as well as front splitters, xenon headlights, fog lights, a glass sunroof, a trunk lid spoiler, and quad exhaust outlets.

The car rides on Bilstein coilover suspension with aftermarket sway bars. The brakes were sourced from an F80 M3, and 19″ ZCP-style wheels wear staggered Michelin tires that are said to have been recently installed.

The heated and power-adjustable front sport seats are gray Nappa leather, and the cabin features a black dashboard with Titan Shadow trim accents. Interior amenities include cruise control, navigation, and automatic climate control. Bavsound speakers and a short-shift kit have been fitted.

The multifunction leather-wrapped steering wheel features M-color stitching and frames a 185-mph speedometer and a tachometer with a variable redline along with gauges for coolant temperature, oil temperature, and fuel level. Auxiliary gauges are mounted on the column. The digital odometer indicates 30k miles, approximately 1,500 of which were added under current ownership.

The 3.2-liter S54 inline-six was rebuilt by Pure Performance with forged pistons, connecting rods, a performance crankshaft, and a high-performance oil pump and bearings. The Stage 2 supercharger is from Active Autowerke and is intercooled, and ID1040 injectors, a methanol-injection system, a TiAL blow-off valve, an oil cooler, a 120mm crankshaft pulley and hub, and a 535 LPH fuel pump were installed. The car is currently tuned for E85 fuel, and the seller states that it can run on 91-octane and more.

The engine was previously tuned by HTE Performance Tuning​​, at which time peak output was measured at 612.84 horsepower. The seller notes that estimated wheel horsepower is currently 540, stating that a factory crank pulley has since been reinstalled in place of an aftermarket larger crank pulley.

The six-speed manual transmission is linked to a limited-slip differential and has a twin-disc clutch. A subframe reinforcement kit was installed in 2022, and aftermarket catalytic converters were also fitted.

Records documenting the modifications are presented in the gallery.

The Carfax report shows no reported accidents or damage. An odometer reading of 29,800 miles was recorded in March 2025, and the title also lists this reading.

The car has not been inspected by the California Air Resources Board or Bureau of Automotive Repair. The seller states the car will not pass a California emissions inspection in its current configuration; therefore, it cannot be sold to an in-state private-party buyer.
