The 2003 Mercedes-Benz M-Class belongs to the first-generation luxury SUVs from Mercedes, offering respectable off-road capabilities alongside its signature Mercedes-Benz luxury. Under the hood, an array of engine options was provided, including a 3.7L V6 engine with 232 horsepower in the ML350 and a 5.0L V8 with 288 horsepower in the ML500. Paired with a 5-speed automatic transmission, the M-Class comes with a standard All-Wheel Drive (AWD). Notable features include the standard TeleAid communications system, side curtain-type airbags, and an Electronic Stability Program. On the tech front, an optional COMAND system was offered, integrating navigation, audio, and telecommunication functions. Despite its advanced features, the M-Class faced criticism over build quality and reliability during this era.
