Judging by the design of the driver door, I’m guessing this is a 90’s Sambar, which indeed does have a bed length of 6.5ft and a width of 4.5ft.
Also, this is normal: “They generally have 1.8 m (6 ft) pickup beds with fold-down sides; dump and scissor-lift beds are also available, as are van bodies. The length limitation forces all of these models into a cab-forward design.”
