2003 BMW M3 Convertible 6-Speed

Description

The 2003 BMW M3 is part of the celebrated E46 generation, produced from 2000 to 2006 and widely regarded as one of BMW’s finest driver-focused cars. By 2003, the M3 had firmly established its reputation, thanks to a blend of balanced handling, motorsport engineering, and everyday usability. Under the hood sat the high‑revving 3.2‑liter S54 inline‑six, producing 333 horsepower in North American spec and paired with either a six‑speed manual or BMW’s SMG II sequential gearbox.

The 2+2 model also featured flared fenders, quad exhausts, and unique aerodynamic touches that distinguished it from the standard 3-Series. The 2003 model year continued refining the formula with improved electronics and subtle interior updates, while retaining hallmark components like the variable M Differential Lock and advanced suspension geometry. As with the prior generation M3, a convertible with an insulated fabric soft top remained available.

Finished from the factory in Steel Gray Metallic paint with a black convertible top over black leather sport seats, this M3 Convertible features the conventional 6-speed manual transmission. Modifications include a K&N High-Flow intake kit, Billy Boat exhaust system, a rear subframe and chassis reinforcement kit, and tinted windows. It now shows approximately 86,700 miles

This 2003 BMW M3 Convertible is now offered by the selling dealer with an owner’s manual, tools, a wind deflector, removed stock parts, documentation for installed modifications, a clean CARFAX history report, and a clean Pennsylvania title.
