1: Isuzu Hombre
GM continued to rebadge Isuzu cars well into the 1990s. In exchange for that, they offered the Japanese automaker an S10 to sell. The Hombre was about as barebones as you could get from the trim packages to its advertising. It did have a slightly more handsome face than the S10 but that wasn’t enough to justify the truck (via The Truth About Cars).
You’d have to be a very dedicated GM enthusiast to even remember this truck as there are very few of them that are still on the road today. Nevertheless, the Hombre was not the last pickup truck that was shared by GM and Isuzu as the Colorado/Canyon came a few years later.
