Isuzu is still in the US market and apparently does well.

They have a truck dealer in my own home town. I even stopped in there once to see if they could order me SUV parts, but they said no. They don't have the catalogs and software to even look up SUV parts.
Isuzu has been well known for a long time as makers of the best diesel engines in the world.
