The 2003 Chevrolet Blazer, a rugged and reliable SUV, marked the final year of production for this iconic nameplate. Introduced in 1995, the Blazer had become synonymous with practicality and off-road capability. This generation, however, transitioned into a more refined and car-like design, departing from its earlier truck-based origins. While still offering a commanding presence and ample cargo space, the 2003 Blazer focused on delivering a smoother ride and improved interior comfort. Power came from a choice of two engines, the base 4.3L Vortec V6, known for its fuel efficiency and robust reliability, or the more powerful 5.3L Vortec V8, delivering a satisfying punch. These engines were coupled with either a four-speed automatic transmission for the V6 or a four-speed automatic transmission with overdrive for the V8.

The 2003 Blazer was available in both two-door and four-door configurations, offering seating for four or five passengers, respectively. Features included power windows and locks, air conditioning, and a premium audio system. Some trim levels also came equipped with leather upholstery, cruise control, and a rear-seat entertainment system. Safety features were equally comprehensive, including dual front airbags, anti-lock brakes, and side impact beams in the doors. While known for its practicality and comfortable driving experience, the 2003 Blazer's fuel economy was considered a weakness, especially in comparison to its more fuel-efficient competitors. Nonetheless, its ruggedness, spacious interior, and versatility made it a popular choice for families and individuals seeking a reliable and capable SUV.
