The Toyota Sienta, which starts at JPY 2M, seems like a much better value for a passenger car - and I think they borrowed from the Kangoo's styling a bit for the latest iteration [2]. Or for business use a Town Ace, NV200, HiJet, etc.
* protects your goods from weather
* more cargo volume
* better forward visibility without a long hood
* easier to load and unload due to being lower
* can park it without people being able to walk up to it and taking your tools and equipment out of the exposed truck bed

(Can an American tell me what these vehicles are called in the USA?)
Flatbeds.
Here they are very common on construction sites for the messier work (building roads, railways, walls, roofs, forestry etc) but normal vans with a roof are more common for the cleaner work (plumbing, electrics, painting, carpentry etc).
I can fit a bed, 3 months of luggage and a bicycle in mine. In a pinch, it's a brilliant microcamper. It's a big box on wheels. You can do what you want with it.
It's not a nice car, but it was designed to serve real user needs. That's why they're everywhere from Morocco to Poland.
