I had the Daihatsu version (1993 model) for 12 years before selling it and moving to the Pioneer 500.
It was a great truck. I put a 2" lift on it, upgraded the front springs and put 25" tires. In the years that I owned it, I did have to replace the fuel pump and carb, but it's basically a 3-cylinder car engine. It's very quiet, can carry a ton and can really climb. I loved the windshield and wipers in the rain. Parts were readily available because there's a guy up in MO (G&R Imports) that has a bunch of used and new parts and can get parts from Japan.
Here's what I didn't like: I'm 6' and was just a little too tall for the leg room. After 12 years I kind of got tired of it. I wanted to replace it with an ATV, but when I saw the 500, I thought it was perfect. Not too big, like the Daihatsu, but a little more leg room. I'll try it for a few years and see how it goes.
