Chevrolet Gmc Trucks:
Chevrolet and GMC have a long history of producing light and medium-duty commercial vehicles. The N-Series represents their entry into the tilt-cab segment, often a rebadged Isuzu.
N Series Development:
The N-Series platform evolved from Isuzu's global truck offerings, tailored for the North American market through GM's branding and distribution channels starting in the early 2000s.
Manufacturing Locations:
Typically assembled in North America (e.g., Indiana, USA) or imported from Isuzu's international manufacturing facilities.
