What are the restrictions of Wuling sealed window vans?

[DeLucille]

Wuling sealed window vans have an obvious exterior restriction - all windows except the first row are completely sealed, hence the name "sealed window van". Essentially a cargo-type microvan, but compared to regular microvans, the sealed window version is longer and uses heavier-duty rear leaf springs than standard microvans to better handle heavy loads. Here's an extended introduction: Window introduction: Car windows are an essential component of the vehicle body, designed to meet requirements for interior lighting, ventilation, and visibility for drivers and passengers. Windows are categorized by installation position: front/rear windshields, side windows, and door windows. The design structure and quality of windows significantly impact driver visibility, passenger comfort, exterior aesthetics, and aerodynamic characteristics. Window structures are typically curved and sealed, with rubber sealing strips connecting the window frame to the glass. These seals provide both sealing and cushioning functions to prevent windshield damage when body forces cause frame deformation.
