== Design == Unusually, the rear door is used for loading, while passengers disembark in the other doors. There is a half door and a double door located in the front section, where the motor is housed, and one door at the rear section. These vehicles represent a design change from previous vehicles built up to the 1990s, with the passenger compartment being designed to allow as many passengers as possible. Hence, most of the seats are single seats with double seats over the wheel wells, which already occupy some space. The driver's cabin is not separate from the passenger cabin, unlike vehicles built prior to 1986.
