Isuzu Truck Legacy:
Isuzu has a long-standing reputation for producing durable and reliable diesel engines and commercial vehicles, which heavily influenced the Rodeo/Colorado platform.
Tf Series Development:
The TF series Rodeo/Colorado (introduced globally in the late 1990s and updated through the early 2000s) represented a significant step in Isuzu's utility vehicle design, offering improved refinement and capabilities over its predecessors.
Manufacturing Locations:
Primarily manufactured in Japan (Isuzu), Thailand (Isuzu Motors Thailand), and Australia (Holden assembly plants).
Model Lifespan:
The TF series ran from approximately 1997 to 2002/2003, with updates and facelifts extending its life into the 2003-2008 period for specific markets under various names. It was eventually succeeded by the global D-Max platform (which also formed the basis for later Holden Colorados).
