The 2003 Mitsubishi Montero, a rugged and capable SUV, marked the end of an era for the iconic nameplate in its original form. This generation, known as the "Gen 3" Montero, was introduced in 1999 and offered a blend of off-road prowess and on-road comfort, making it a popular choice for both adventure seekers and families. Power came from either a 3.5-liter V6 engine producing 200 horsepower or a larger 3.8-liter V6 generating 215 horsepower. Both engines were mated to a four-speed automatic transmission, delivering smooth acceleration and reliable performance. The Montero's robust ladder frame construction, coupled with a sophisticated four-wheel drive system, enabled it to tackle challenging terrain with ease. Features like a low-range transfer case, locking differentials, and generous ground clearance allowed it to conquer obstacles and navigate rough roads with confidence. The 2003 Montero also offered a comfortable and well-appointed interior, with spacious seating for five passengers and ample cargo room. Despite its enduring popularity, the 2003 Montero faced increasing competition from more modern SUVs with advanced features and fuel-efficient engines. Mitsubishi opted to discontinue the Montero in the United States in 2006, marking the end of an era for the iconic SUV. However, the legacy of the Montero lives on, with many enthusiasts and off-road enthusiasts still enjoying the rugged capabilities and timeless design of this generation. The Montero's reputation for durability and reliability continues to attract buyers seeking a capable and dependable SUV for off-road adventures or everyday driving. While a repair service manual for the 2003 Montero is essential for maintaining and repairing this vehicle, the model's strong construction and straightforward design make it relatively easy to work on, even for experienced home mechanics. Finding a trusted and reputable repair shop specializing in Mitsubishi vehicles is also an option for owners seeking professional service.
