It should be pointed out, that even if they brought what you're talking about here, it likely wouldn't be cheap.
The Colorado is only like $5k less than a full size Chevy, and is pretty much crap.
A base Tacoma is $5k less than a base F150.
That Toyota I posted up there is $33,000 base price!
I'd bet that the real reason we don't have those smaller, tough trucks over here is that for what they'd cost, Americans would just buy a bigger one. The same reason we don't have the nice compact cars of Europe and Asia.
My first truck was an 82 Datsun, then I went to a '94 Toyota SR5. Both were 4wd. I drove both in AK, towing and hauling. Both were good, capable trucks, that were reliable and ran well. Neither had ANYTHING like the ride comfort, cabin, or options that appear to be desirable to American buyers these days. and neither got particularly good gas mileage. Assuming that the current 70 series trucks are just as tough and capable as my SR5 was, and looking at what they cost, and having actually driven one.......I'd buy an F150 FX4 all day long. They are cool though. If they could make one with some options for ~$22k it'd be a contender.
