It doesn't have seat belts. It's a window cargo van.
Funeral homes and flower shops liked 'em for hauling daises......
If you see one they are usually in good shape.
Most of the government/military/airport cargo vans I've seen had windows.
Some countries charge a higher import fee for "panel vans" so a lot of the US brand cargo vans overseas have windows.
Because of the blind spot, utility companies would order cargo vans with windows in the right side to get a break on insurance. (display vans we call 'em)
