The most indestructible (other than brakes) "beater" pickup I ever owned was a used Mazda B2000 bench seats, rubber mats, "power" nothing and a power train that would not quit. It rusted away in the same pattern as it's siblings, but it never actually gave up the ghost. The plain vehicles that provided reliable, faithful basic hauling/transportation are the ones that I remember with the most fondness. I wish I could be similarly nostalgic about my Dodge Dakota, but I'm not.

My dad had one of those Mazda B2000 trucks, manual choke. Engine was fairly agricultural which is to say not particularly smooth or quiet but it was indestructible. Good little truck. Formerly the Ford Courier, I believe.
