Maybe 5 or 10 years ago, I remember a radio and TV campaign for Isuzu pickup trucks. They were cheap, supposed to be a fleet replacement option, and then completely disappeared from radar.
This morning at the lumber yard, I was actually parked next to one. 
Not a bad looking truck at all. The one I was parked by had a cap on the back and still looked pretty alright.
So what's the deal with them? Are they just a fleet purchase or was the whole idea terrible and that's why we don't see many of them?
Isuzu was a Japanese company who sold cars and trucks in the US. As things evolved and The Chicken Tax combined with a weak Yen, Isuzu was just left with rebadged GM's. At the end that was a rebadged S-10 called the i-290 and a rebadged Trailblazer called the Ascended (Ass-end-er)
As far as I know, they're just regular GM trucks with different badges on them.
The Colorado and Canyon were built at the Isuzu plant in Louisiana alongside the Isuzu I-series trucks and are essentially the same. Who was the rebadge?
The Hombre was a re-badged S10.
Before that they were their own trucks, and drive train was pretty similar to early Rodeo/Amigos.
Before that they were sold here as Chevy LUVs.
I wonder if this makes them cheaper or more expensive than the GM equivalents.
And here I was hoping I'd spotted a unicorn. Seems they haven't been made in about a decade, but I'm pretty sure this is the only one I've seen out in the wild.
In a perfect world, they should not sell cheaper because they really are the same truck as the GM equivalent. The reality is that trying to sell an Isuzu version will take longer because few people set out looking for an Isuzu or understand the the similarity when they see the Isuzu badge.
This longer sale with fewer real shoppers can very much lead to the ability to buy the Isuzu version cheaper than the GM version. But, keep in mind this works both ways so when it is time to sell the Isuzu, it could be harder to get rid of. However, if your going to keep it a long time and use up most all of the vehicle like I do then by all means shop and search Isuzu to find a "good deal".
I nearly pulled the trigger on one in '06, just before they started closing down dealerships, and at the time they were all extended or crew cabs being sold at roughly the same price as the regular or extended cab Chevys. They had a better warranty, though, 5-year 60k vs 3-year 36k for the GM versions.
Isuzu still makes their own (compact) pickups, but they're not sold in the US. The Isuzu Dmax is very common by me, it's about the size of a 4th-gen Toyota Pickup/Hilux.
Neighbor had a P'UP or however it's spelled.
Loved that truck!
